Installed at the master cylinder brake outlet, the banjo bolt clamps the banjo fitting in place and allows brake fluid to pass through its drilled channels under pressure. Because it sits in a high-pressure circuit, correct fit and condition are essential for leak-free operation.

Old banjo bolts can corrode, round off, or suffer sealing-surface wear, which increases the risk of brake fluid leaks and loss of hydraulic pressure. Replacing with a fresh bolt helps restore a secure connection and supports safe, reliable braking.

When to replace:
•  Brake fluid seepage around the banjo fitting/master cylinder
•  Corrosion, damaged threads, or rounded bolt head
•  During master cylinder replacement or brake line refurbishment
•  When rebuilding a classic brake system using new lines/fittings

Diagram Ref No 27

This specialised hollow bolt is used to secure a banjo-style brake line fitting to the appropriate brake caliper or wheel cylinder. Unlike a conventional solid bolt, it contains an internal passage that allows hydraulic brake fluid to flow through the connection.

Manufactured to Porsche's original equipment specifications, the banjo bolt provides both mechanical fastening and a hydraulic fluid passage within the braking system.

When the driver presses the brake pedal, the master cylinder generates hydraulic pressure that travels through the brake lines to the relevant brake calipers or wheel cylinders.

The banjo bolt allows this pressurised fluid to pass through the connection while holding the banjo fitting securely in position.

When installed with the correct sealing washers and tightened to the specified torque, the assembly helps maintain a leak-free hydraulic connection.

Although a relatively small component, the banjo bolt performs an essential function in the braking system.

Over time, the original bolt may become damaged through corrosion, overtightening, repeated removal, cross-threading or incorrect installation. The internal fluid passage may also become obstructed by contamination.

Damaged threads, distorted sealing surfaces or excessive corrosion can compromise the connection and potentially cause brake fluid leakage.

Loss of hydraulic fluid or pressure can affect braking performance and represents a significant safety concern.

Replacing a damaged or defective banjo bolt with a Genuine Porsche component helps restore secure brake line attachment, maintain hydraulic system integrity and support reliable braking operation.

Ideal for classic Porsche brake repairs, caliper refurbishment, wheel cylinder servicing and restoration projects, this Genuine Porsche Banjo Bolt provides a factory-specified replacement for compatible applications.

What This Product Does:
The banjo bolt is a hollow hydraulic fitting used to connect brake pipework to the appropriate braking component.

Its primary functions are to secure the banjo fitting mechanically and allow pressurised brake fluid to pass through the connection.

When the brake pedal is depressed, hydraulic pressure is generated by the master cylinder and transmitted through the brake fluid.

At the banjo connection, fluid passes through the bolt's internal drilling and into the connected brake caliper or wheel cylinder.

The bolt and its sealing washers must maintain the connection without allowing brake fluid to escape.

Its main functions include:

• Securing the brake line connection: Holds the banjo fitting in position against the connected brake component.
• Allowing brake fluid flow: Provides an internal passage for hydraulic brake fluid.
• Maintaining hydraulic pressure: Helps preserve the sealed brake circuit when correctly installed.
• Supporting braking performance: Allows pressure to reach the relevant brake caliper or wheel cylinder.
• Providing a secure mechanical connection: Maintains the attachment between the banjo fitting and braking component.
• Supporting hydraulic sealing: Works with the specified sealing washers to prevent leakage.
• Withstanding braking pressure: Operates under repeated hydraulic pressure changes.
• Maintaining original brake system configuration: Preserves the factory-style connection arrangement.
• Supporting brake system servicing: Allows damaged or corroded fittings to be replaced.
• Preserving component compatibility: Provides the specified fitting arrangement for compatible original Porsche brake components.

Symptoms Of Wear Or Failure:
A banjo bolt does not normally wear through movement, but it may become damaged through age, corrosion, mechanical stress or incorrect servicing.

Common signs of a damaged or defective banjo bolt include:

• Brake fluid leakage: Fluid may escape around the banjo fitting or bolt connection.
• Wetness around the connection: Visible brake fluid may collect around the caliper or wheel cylinder.
• Falling brake fluid level: A leaking connection may cause the master cylinder reservoir level to decrease.
• Soft or spongy brake pedal: Fluid loss and air entering the hydraulic circuit may affect pedal feel.
• Excessive brake pedal travel: A significant hydraulic fault may result in increased pedal movement.
• Reduced braking effectiveness: Severe fluid loss or pressure loss can compromise braking performance.
• Damaged bolt threads: Stripped or distorted threads may prevent secure installation.
• Cross-threading: Incorrect installation may damage both the bolt and the receiving component.
• Visible corrosion: Rust or surface deterioration may weaken the fitting.
• Pitting around sealing surfaces: Corrosion or damage may prevent the sealing washers from seating correctly.
• Rounded bolt head: Previous servicing damage may make removal or correct tightening difficult.
• Cracked or distorted bolt: Excessive tightening or mechanical damage may compromise the component.
• Blocked internal passage: Contamination may restrict brake fluid flow.
• Persistent leakage after servicing: Incorrect washers, damaged sealing surfaces or improper installation may prevent a reliable seal.
• Inability to tighten correctly: Damaged threads or incorrect bolt dimensions may prevent proper fastening.

Why Replacement Matters:
Replacing a defective banjo bolt is important for maintaining the safety and reliability of the vehicle's hydraulic braking system.

A damaged bolt may no longer provide secure mechanical attachment or a properly sealed passage for brake fluid.

If the connection leaks, hydraulic pressure may be lost and air may enter the system, potentially reducing braking performance.

Continued operation with a damaged banjo bolt may also worsen damage to the associated brake fitting or caliper threads.

Installing a Genuine Porsche replacement Banjo Bolt helps to:

• Restore secure brake line attachment: Replace a damaged or unreliable fastening component.
• Maintain hydraulic system integrity: Support a correctly sealed brake fluid connection.
• Prevent brake fluid leakage: Address leaks caused by a confirmed defective bolt.
• Restore reliable fluid flow: Replace a bolt with a damaged or obstructed internal passage.
• Maintain effective braking: Support proper hydraulic pressure delivery to the connected component.
• Reduce the risk of sudden connection failure: Replace cracked, severely corroded or damaged hardware.
• Prevent further thread damage: Renew damaged fittings before associated components are affected.
• Support brake caliper servicing: Provide an original equipment fitting during caliper repairs.
• Support wheel cylinder refurbishment: Restore the correct connection on compatible drum brake assemblies.
• Maintain original specifications: Preserve Porsche's intended banjo fitting arrangement.
• Support classic Porsche restoration: Replace deteriorated original brake hardware.
• Maintain Genuine Porsche quality: Use an original equipment replacement for a safety-critical component.

Replacement is recommended when the bolt is cracked, severely corroded, cross-threaded, distorted or unable to provide a secure hydraulic connection.

Where leakage originates from the sealing washers rather than the bolt itself, the correct replacement washers may resolve the issue, provided the bolt and mating surfaces remain serviceable.

Diagram ref no 11

Although small, this connection piece forms an important part of the hydraulic braking system. A secure, correctly sealed connection helps maintain brake fluid pressure between the rigid brake pipe and associated hydraulic components.

What Does the Brake Hose / Line Connection Piece Do?

The connection piece provides a secure joining point within the vehicle's hydraulic brake circuit.

When the brake pedal is pressed, hydraulic pressure generated by the master cylinder must travel through the brake pipes and flexible hoses to the brake calipers or wheel cylinders. Every connection within this system must remain securely sealed to prevent loss of brake fluid and hydraulic pressure.

Why Is It Important?

The braking system relies on a closed hydraulic circuit. Even a relatively small leak at a brake line connection can result in fluid loss and reduced braking effectiveness.

A correctly fitted connection piece helps:

• Provide a secure brake hose/line connection
• Maintain the integrity of the hydraulic brake circuit
• Prevent brake fluid leakage at the joint
• Maintain correct factory brake line routing
• Provide the correct connection when replacing brake pipes or hoses
• Restore the original brake system during a classic Porsche restoration

Because it forms part of a safety-critical hydraulic system, the fitting and surrounding brake lines should always be inspected carefully during brake servicing.

Why Does It Fail?

Metal brake fittings can deteriorate after decades of service, particularly on classic Porsche models exposed to moisture, road dirt and road salt.

Common problems include:

• External corrosion
• Damaged or rounded threads
• Seized brake pipe fittings
• Damage during removal of old brake hoses or pipes
• Distorted sealing surfaces
• Previous overtightening
• Cross-threading
• Contamination around the connection
• General deterioration associated with age

Older fittings can also become extremely difficult to separate from the brake pipe after many years in position. Attempting to force a seized connection may damage the fitting or adjoining brake line.

When Should It Be Replaced?

Replacement should be considered if the connection piece is corroded, damaged, seized or no longer provides a reliable hydraulic connection.

It is also sensible to inspect and, where necessary, replace the fitting when installing:

• New brake hoses
• Replacement rigid brake pipes
• New brake calipers
• Refurbished brake calipers
• A replacement master cylinder
• A completely restored braking system

Any evidence of brake fluid leakage around the connection requires immediate investigation.

Checks and Diagnosis

Before replacing the connection piece, inspect the surrounding braking system carefully.

Check the rigid brake pipe for corrosion or damage and inspect the flexible hose for cracking, swelling, abrasion or deterioration. Check the threads and sealing surfaces of all mating components and look for signs of brake fluid leakage.

If the brake pedal feels unusually soft or requires excessive travel, the complete hydraulic system should be checked rather than assuming the connection piece itself is responsible.

After opening the hydraulic circuit, the brake system must be correctly bled and checked for leaks before the vehicle is returned to use.

Required Quantity

• Porsche 911 1970–73: 4 retaining springs in the brake hydraulic assembly.
• Porsche 911 1974–77 without brake booster: 4 retaining springs in the brake-line assembly.
• Porsche 911 1978–83, 1984–86 and 1987–89: 2 retaining springs in the front brake-line assembly and 2 in the rear brake-line assembly.

What Is This Part?
This is the retaining spring used at a brake hose mounting point. The hose end fitting sits in a bracket, and the clip keeps it seated there while the flexible hose accommodates movement. It forms part of the hose mounting arrangement alongside the bracket and connected rigid brake pipe. Its role is mechanical retention; the hydraulic connection itself must also be correctly assembled and checked. 

What Does This Part Do?

• Retains the hose fitting: Keeps the end fitting seated in its mounting bracket.
• Restrains unwanted movement: Helps prevent the fitting moving out of its supported position.
• Completes the mounting arrangement: Works with the bracket to secure the hose at the connection to the rigid brake pipe. 

Why Replace This Part?
Replace the clip if inspection finds significant corrosion, cracking, distortion or a loss of grip that prevents it retaining the fitting correctly. Damage during removal can also leave a clip unsuitable for refitting. A new clip should be considered on its condition, rather than automatically replaced whenever other brake components are serviced.

If the hose fitting is loose, inspect the bracket and fitting as well as the clip. Worn or damaged supporting parts may prevent secure seating even with replacement retaining hardware.

When to Replace This Part?

• Corrosion: Heavy rust or material loss has weakened the clip.
• Visible damage: The clip is bent, cracked or distorted.
• Poor retention: The clip no longer holds the fitting securely after the mounting arrangement has been checked.
• Missing hardware: The correct retaining clip is absent from a mounting point.
• Removal damage: Inspection during hose replacement shows that the existing clip cannot be refitted securely.

Where Is This Part Fitted?
Location: At the brake hose end fitting where it is retained in a mounting bracket beside the rigid brake pipe connection. Applicable Porsche 911 installations include front and rear brake-line assemblies; the exact mounting points depend on the vehicle.
