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.

    The required quantity depends on the caliper and axle assembly. Some Porsche diagrams specify four valves for a complete axle assembly, while this product contains two.
  • When should a bleed valve be replaced?
    Replacement is appropriate when the valve is seized, leaking, blocked, physically damaged or unable to seal correctly.

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.

Brake caliper bracket mount thread repair fixture

stomski

Another STOMSKI RACING original, this ingenious tool is designed primarily for the "younger" Porsches (Caymans, Boxsters, Cayennes, 996s, 997s, GT3s, etc.) that are experiencing pulled threads in the aluminum suspension parts where the brake calipers bolt up (usually in the rear).

The SR152 fixture adjusts from a bolt hole spacing of 4.5" to about 6.5" allowing application for a wide range of vehicles.
It comes complete with 4 different bushings to help align the tool, and then guide all the tools of the TimeSert M12 kit (sold separately).

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.
