Product Information
Product Information
Brake Caliper Bleed Nipple.
The OE Match Brake Caliper Bleed Nipple is a precision-engineered brake hydraulic component designed to facilitate the removal of air from the braking system during maintenance and servicing procedures. Manufactured to OE specifications for fit, thread accuracy and sealing performance, this bleed nipple plays a vital role in maintaining the efficiency and safety of the vehicle's braking system.  

Fits:
  • Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
  • Porsche 911 1978-1983 3.0L / SC  

Diagram Ref No 10

Constructed from high-quality corrosion-resistant metal, the bleed nipple provides a secure hydraulic seal during normal operation while allowing controlled release of air and brake fluid during brake bleeding. Its precision-machined design ensures reliable installation and dependable performance under the high pressures encountered within the brake hydraulic circuit.  

What This Product Does:
  • Allows air to be removed from the brake hydraulic system.
  • Facilitates brake bleeding and fluid replacement procedures.
  • Helps maintain proper hydraulic pressure within the braking system.
  • Supports a firm and responsive brake pedal feel.
  • Provides a secure seal during normal brake operation.
  • Enables effective servicing of brake calipers.
  • Contributes to safe and reliable braking performance.
  • Forms an essential component of the brake caliper assembly.

Symptoms Of Wear Or Failure:
  • Brake fluid leaks around the bleed nipple.
  • Soft or spongy brake pedal feel.
  • Difficulty bleeding the brake system.
  • Rounded or damaged bleed nipple head.
  • Seized or corroded bleed nipple threads.
  • Air entering the hydraulic system.
  • Reduced braking performance.
  • Fluid seepage from the caliper.
  • Difficulty achieving a proper hydraulic seal.
  • Brake warning indications due to fluid loss.

Why Replacement Matters:

  • Brake bleed nipples are exposed to moisture, road salt, brake fluid, heat cycles and repeated servicing throughout their lifespan. Over time, corrosion can cause the nipple to seize, while damaged threads or sealing surfaces can lead to fluid leaks and compromised hydraulic performance.
  • A faulty bleed nipple can make routine brake maintenance difficult and may prevent the complete removal of air from the hydraulic system. Trapped air can reduce braking efficiency, create a soft brake pedal and compromise vehicle safety. Fluid leaks can also lead to pressure loss and reduced braking performance.
  • Replacing a worn or damaged bleed nipple restores proper sealing and ensures effective brake system servicing. An OE Match replacement provides factory-style fitment, dependable sealing characteristics and long-lasting durability, helping maintain the braking performance, safety and reliability expected from your Porsche.

Porsche 911 1974 - 1983 2.7L / 3.0L SC

These OE match front brake calipers are direct replacement units engineered to replicate the original Porsche “A-Type” calipers fitted to 911 models from 1974 to 1983. Designed for vehicles equipped with 2.7L and 3.0L SC engines, they integrate seamlessly into the factory braking system.

Each caliper is side-specific and sold separately:
  Left (driver side): 91135142502
  Right (passenger side): 91135142602

These units are designed for direct bolt-on installation and are compatible with original brake discs and pads, making them ideal for restoration, maintenance, or performance reliability upgrades.

The brake caliper clamps the brake pads against the brake disc when the brake pedal is pressed. This creates friction, slowing the rotation of the wheel and bringing the vehicle to a controlled stop. The fixed design ensures consistent braking performance and even pad wear.

Function
•   Applies braking force to discs via brake pads
•   Distributes pressure evenly across the braking surface
•   Converts hydraulic pressure into mechanical braking force
•   Supports stable, controlled stopping performance
•   Ensures consistent braking response under load

Brake calipers are exposed to heat, moisture, and constant mechanical stress. Over time, seals can degrade, pistons can seize, and corrosion may affect performance. Worn calipers can lead to uneven braking, reduced stopping power, and increased wear on discs and pads. Replacing them restores braking efficiency, safety, and driving confidence.

When to replace
  Brake caliper sticking or seized piston
  Uneven brake pad wear
  Reduced braking performance or pulling to one side
  Fluid leaks around caliper seals
  During brake system overhaul or restoration

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.
