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.

FAQs
- What is included?
A pack containing two brake caliper bleed valves with cover caps. - Can these valves be used at the front or rear?
They are listed for applicable front and rear caliper installations. Confirm the part number against the specific vehicle and caliper. - How many valves are required?
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.

What Does a Brake Caliper Overhaul Kit Do?
A brake caliper overhaul kit replaces the critical wear components inside the caliper, allowing it to function correctly and safely. New piston seals restore hydraulic sealing, while new dust caps protect the pistons from moisture, dirt and road debris.
The overhaul helps to:
- Restore smooth piston movement.
- Maintain correct hydraulic pressure.
- Prevent brake fluid leaks.
- Protect pistons from corrosion.
- Ensure even brake pad operation.
- Improve pedal feel and braking consistency.
- Extend the life of the original calipers.
A rebuilt caliper delivers braking performance much closer to factory condition while avoiding the cost of complete caliper replacement.
Why Do Brake Calipers Require Overhauling?
Brake calipers are continually exposed to heat, moisture and
contamination. Over time, internal components deteriorate. Common causes
include:
- Heat generated during repeated braking.
- Ageing and hardening of piston seals.
- Split or perished dust caps.
- Moisture entering the caliper.
- Corrosion around the pistons.
- Contaminated brake fluid.
- Seized or sticking pistons.
- Worn bleed valves.
- High mileage and long-term use.
Ignoring worn seals or damaged dust caps can eventually lead to uneven braking, fluid leaks and accelerated brake pad wear.
When Should a Brake Caliper Be Rebuilt?
A caliper overhaul is recommended whenever:
- Pistons begin sticking or seizing.
- Brake fluid leaks are present.
- Dust caps become cracked or damaged.
- Brake pads wear unevenly.
- The calipers are removed for refurbishment.
- During a complete brake system rebuild.
- Preparing the vehicle for fast road or track use.
- As preventative maintenance on older vehicles.
Rebuilding both front calipers together helps maintain balanced braking performance across the front axle.
