The lightweight aluminium S-Caliper was originally developed
to deliver exceptional braking performance while reducing unsprung weight,
making it one of the most recognisable and sought-after brake calipers fitted
to early air-cooled Porsche 911 models. Whether you're carrying out a concours
restoration or replacing worn original components, this OE Match caliper offers
factory-style fit, appearance and dependable braking performance.
The S calipers were first introduced in 1969 on Porsche 911 cars equipped with vented discs. It was also used on Porsche race car model 908. This caliper has 48mm size piston.
What Does the Front Brake Caliper Do?
The front brake caliper is a critical component of your Porsche's braking system.
Its primary functions include:
- Housing the brake pistons that apply pressure to the brake pads.
- Converting hydraulic brake fluid pressure into clamping force.
- Squeezing the brake pads evenly against the brake disc to slow or stop the vehicle.
- Delivering balanced braking performance and pedal feel.
- Helping maintain safe, predictable stopping under all driving conditions.
The lightweight aluminium construction also reduces unsprung weight, contributing to improved steering response, suspension performance and handling.
Why Do Brake Calipers Fail?
After decades of service, brake calipers are exposed to heat, moisture, brake dust and road contaminants, which can eventually affect their performance.
Common causes of failure include:
- Internal corrosion from contaminated brake fluid.
- Seized or sticking pistons.
- Worn or damaged piston seals allowing fluid leaks.
- Corrosion beneath dust seals.
- Damaged bleed screw threads.
- External corrosion and cosmetic deterioration.
- Physical damage caused by impact or improper maintenance.
A sticking or leaking caliper can reduce braking efficiency, increase brake pad wear and compromise vehicle safety.
When Should They Be Replaced?
Replacement is recommended when:
- Brake fluid is leaking from the caliper.
- Pistons seize or fail to retract correctly.
- Uneven brake pad wear is present.
- Braking performance or pedal feel has deteriorated.
- The caliper body has been damaged or heavily corroded.
- Restoring a classic Porsche to factory specification.
- Existing calipers are beyond economical repair.
Replacing worn brake calipers restores braking balance, improves safety and ensures reliable performance.

Manufactured from quality corrosion-resistant metal, the vent valve (bleed screw) provides a secure seal during normal operation while allowing controlled release of air and brake fluid during brake bleeding procedures. Its precision-machined design ensures reliable sealing under the high hydraulic pressures generated within the braking system.
What This Product Does:
- Allows air to be removed from the brake hydraulic system.
- Facilitates brake bleeding and maintenance procedures.
- Ensures proper hydraulic pressure within the brake caliper.
- Helps maintain a firm and responsive brake pedal feel.
- Provides a secure seal during normal brake operation.
- Supports safe and efficient braking performance.
- Prevents hydraulic pressure loss when correctly installed.
- Forms an essential part of the brake caliper assembly.
Symptoms Of Wear Or Failure:
- Brake fluid leaks around the bleed valve.
- Soft or spongy brake pedal feel.
- Difficulty bleeding the braking system.
- Rounded, seized or damaged bleed screw head.
- Corrosion around the vent valve.
- Air repeatedly entering the hydraulic system.
- Reduced braking performance.
- Fluid seepage from the caliper.
- Inability to properly seal after servicing.
- Brake warning indications due to fluid loss.
Why Replacement Matters:
- Brake vent valves are exposed to moisture, road salt, dirt, heat cycles and repeated servicing throughout their lifespan. Over time, corrosion can cause the valve to seize, while damaged threads or sealing surfaces may allow brake fluid leaks or air ingress into the hydraulic system.
- A faulty vent valve can compromise the effectiveness of brake bleeding procedures, resulting in trapped air within the hydraulic circuit and a reduction in braking performance. Even minor fluid leaks can lead to pressure loss, reduced braking efficiency and increased safety risks.
- Replacing a worn or damaged vent valve restores proper sealing and ensures the braking system can be correctly maintained.
