What Does a Brake Caliper Overhaul Kit Do?
Over time, the seals, dust boots and service components inside the brake calipers deteriorate due to heat, age and repeated braking cycles. A caliper overhaul kit restores the internal sealing and protection of the caliper, allowing the pistons to operate smoothly and maintain consistent hydraulic pressure.
The overhaul restores:
- Correct piston sealing.
- Smooth piston movement.
- Protection against water and dirt ingress.
- Proper brake pad operation.
- Reliable hydraulic performance.
- Consistent braking performance.
- Long-term caliper reliability.
A professionally rebuilt caliper can often provide many more years of dependable service.
Why Do Brake Calipers Require Overhauling?
Brake calipers operate in one of the harshest environments
on the vehicle. Common causes of wear include:
- Heat generated during braking.
- Ageing and hardening of rubber piston seals.
- Dust boot deterioration.
- Moisture entering the caliper.
- Corrosion around the pistons.
- Contaminated brake fluid.
- Sticking pistons.
- Seized bleed nipples.
- General wear after high mileage.
Ignoring worn seals can eventually result in sticking brakes, uneven pad wear or brake fluid leaks.
When Should a Brake Caliper Be Rebuilt?
A caliper overhaul is recommended whenever:
- Brake pistons become stiff or seize.
- Dust boots split or perish.
- Brake fluid leaks develop.
- Uneven brake pad wear is evident.
- The calipers are removed for restoration.
- During a complete brake system refurbishment.
- The vehicle is being prepared for fast road or track use.
- As preventative maintenance on ageing vehicles.
Rebuilding both front calipers at the same time ensures balanced braking performance across the axle.

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.
