What This Product Does

A bleed valve provides a controlled outlet for releasing trapped air and old hydraulic fluid during brake system bleeding. Once the procedure is complete, the valve is tightened to seal the hydraulic circuit.

Functions

Provides an outlet during brake fluid bleeding
Allows trapped air to be removed from the caliper
Seals the bleed passage when correctly tightened
Supports routine brake fluid and caliper servicing

Technical Details

Manufacturer: Genuine Porsche
Primary part number: 93035191900
Supplied quantity: Pack of 2
Position: Suitable for applicable front and rear installations
Also identified as a ventilation valve in Porsche parts diagrams
Diagram Ref: No 11 & 12

Symptoms of Fault

Brake fluid seepage around the bleed valve
A seized or corroded valve that cannot be opened
Rounded or damaged tool flats
A blocked bleed passage preventing correct fluid flow
Air remaining in the hydraulic circuit after attempted bleeding
Damage to the valve seat or threads

Why Replacement Matters

A damaged, corroded or blocked valve can prevent the caliper from being bled correctly or may fail to seal against fluid loss. Replacing the affected valve restores access to the bleed passage and supports correct hydraulic system servicing. Inspect the caliper threads and sealing seat before installation, and have brake work completed by a suitably qualified technician.

Check fitment for your specific vehicle (model, year, engine) before ordering.

Why Brake Caliper Bleed Valves Need Replacement ?

Brake caliper bleed valves are exposed to extreme heat, moisture, and road debris, which can cause them to wear out over time. Replacing worn or damaged valves is essential for safe and effective braking.
Common Signs Your Bleed Valves Need Replacement:
Fluid Leaks: Moisture or brake fluid seeping around the threads indicates compromised seals or worn threads.
Seized or Stuck Valves: Difficulty opening or closing the valve during brake bleeding can affect maintenance and safety.
Corrosion: Rust or pitting on the valve surface can impact brake performance.
Damaged Threads: Stripped or worn threads prevent proper sealing, leading to leaks and reduced efficiency.

Typical Causes of Valve Problems:

Thread Wear: Steel valves can wear down aluminum caliper threads over time, causing leaks or operational issues.
Seizing: Over-tightening or corrosion can make valves difficult to operate.
Maintenance Damage: Improper handling or excessive force during brake service can strip or break the valve.
Replacing faulty bleed valves ensures brake fluid remains clean and free of air, keeping your braking system safe and reliable.

Diagram Ref No 8

Installed in the brake caliper, the bleeder valve provides a controlled point for releasing trapped air and old brake fluid when bleeding or servicing the hydraulic braking system. When closed, the valve must seal securely to maintain the integrity of the hydraulic circuit.

Because the braking system depends on correctly pressurised hydraulic fluid, a damaged, corroded, seized or leaking bleeder valve should not be ignored. Replacement helps ensure the caliper can be properly bled while maintaining a reliable fluid-tight seal during normal braking operation.

What This Product Does:
The bleeder valve provides a service point for removing air and old brake fluid from the hydraulic brake system.

During the brake-bleeding procedure, the valve is opened in a controlled manner so that brake fluid and trapped air can leave the caliper.

Once bleeding is complete, the valve is tightened to create a secure hydraulic seal.

Its main functions are to:

Provide a controlled brake-bleeding point
Allow trapped air to be removed from the caliper
Allow old brake fluid to be flushed during servicing
Help achieve a firm and consistent brake pedal
Seal the hydraulic system when closed
Support correct brake maintenance and fluid replacement

Although physically small, the bleeder valve performs an important role in maintaining and servicing the braking system.

Symptoms Of Wear Or Failure:
Common signs that a brake caliper bleeder valve may require replacement include:

Brake fluid leaking around the valve
Valve will not seal correctly
Seized bleeder valve
Heavy corrosion
Rounded or damaged hex
Damaged threads
Damaged valve seating surface
Valve broken during removal
Restricted or blocked fluid passage
Difficulty bleeding the caliper
Brake fluid continues to seep after tightening
Missing or damaged dust cap
Previous overtightening damage

Any brake-fluid leak should be investigated immediately.

Why Replacement Matters:
Replacing a worn, seized or damaged brake caliper bleeder valve helps maintain both the serviceability and hydraulic integrity of the brake system.

A correctly functioning replacement helps:

Provide a reliable brake-bleeding point
Allow trapped air to be removed
Support proper brake-fluid changes
Maintain a secure hydraulic seal
Prevent brake-fluid leakage from a defective valve
Restore future serviceability of the caliper
Protect the bleed point with the supplied dust cap
Support consistent brake-system operation

Because this component is part of the hydraulic braking system, defects should be addressed promptly.

About Brake Calipers

Porsche Brake Calipers | Design911 Precision Replacement & Performance Upgrades for Stopping Power & Control

Brake calipers are a vital part of your Porsche’s braking system — responsible for clamping the brake pads against the disc to create friction and slow the car safely and efficiently. They play a key role in delivering the sharp, responsive braking feel Porsche is renowned for. Whether you’re restoring a classic model or enhancing a modern performance car, maintaining or upgrading your calipers ensures consistent stopping power and driving confidence.

At Design911, we offer a wide selection of brake calipers engineered for precision performance, exact fitment, and long-term reliability. Each caliper is designed using high-quality materials to provide superior heat dissipation, even pressure distribution, and enhanced braking control. Ideal for road, track, or restoration projects, our calipers deliver the perfect blend of safety, strength, and Porsche performance heritage.

What Do Brake Calipers Do?

Brake calipers are the heart of the braking system, converting hydraulic pressure into mechanical force to bring your Porsche to a controlled stop.

Core Functions:
• Apply pressure to the brake pads for effective friction and deceleration.
• Ensure even braking force across each wheel.
• Maintain consistent braking feel and performance under heat and load.
• Work with brake discs and pads to optimise stopping distance.
• Provide responsiveness and control during aggressive driving or track use.

A well-functioning brake caliper guarantees stability, safety, and precision every time you hit the brakes.

Why Do Brake Calipers Fail or Degrade?

Over time, brake calipers are exposed to extreme heat, pressure, and environmental conditions — all of which can cause performance degradation or mechanical failure.

Common Causes of Failure Include:
• Corrosion or rust on pistons and seals.
• Leaking hydraulic fluid from worn seals or connections.
• Uneven brake pad wear due to sticking pistons.
• Fading performance from heat saturation and lack of maintenance.
• Physical damage from impact or excessive vibration.

When calipers fail, braking performance becomes inconsistent or unsafe — making replacement or refurbishment essential for maintaining control and confidence.

Why Replace or Upgrade Your Porsche Brake Calipers?

Replacing old or worn brake calipers restores your Porsche’s braking precision and safety. Upgrading to performance calipers can further enhance stopping power, consistency, and resistance to brake fade. Design911 offers options tailored for both daily driving and motorsport use.

Key Benefits:
• Restores even and powerful braking performance.
• Improves safety and pedal feel during high-demand conditions.
• Enhanced heat management and durability.
• Available in performance and original-spec styles.
• Direct-fit design for Porsche-specific applications.
• Perfect for road, track, or restoration builds.

Design911’s Porsche brake calipers deliver the balance of power, control, and endurance your Porsche deserves — engineered for precision and longevity.

Highlights

• Premium Porsche brake calipers for performance and restoration.
• Manufactured from durable, heat-resistant alloys.
• Available for classic and modern Porsche models.
• Precision-engineered for balanced braking performance.
• Ideal for daily driving, track use, or concours restoration.
• Designed for exceptional strength and reliability.
