Brake Caliper Bleed Nipple. Porsche 911 1974-83 ❭ 91135191901
- Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera
- Porsche 911 1978-1983 3.0L / SC
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.
