Information
Brake caliper FRONT
Caliper fixing points are 90mm apart.
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

Why Brake Caliper Bleed Valves Need Replacement ?
- Brake caliper bleed valves are exposed to extreme heat, moisture, and road debris, which can cause them to wear out over time. Replacing worn or damaged valves is essential for safe and effective braking.
- Common Signs Your Bleed Valves Need Replacement:
- Fluid Leaks: Moisture or brake fluid seeping around the threads indicates compromised seals or worn threads.
- Seized or Stuck Valves: Difficulty opening or closing the valve during brake bleeding can affect maintenance and safety.
- Corrosion: Rust or pitting on the valve surface can impact brake performance.
- Damaged Threads: Stripped or worn threads prevent proper sealing, leading to leaks and reduced efficiency.
Typical Causes of Valve Problems:
- Thread Wear: Steel valves can wear down aluminum caliper threads over time, causing leaks or operational issues.
- Seizing: Over-tightening or corrosion can make valves difficult to operate.
- Maintenance Damage: Improper handling or excessive force during brake service can strip or break the valve.
- Replacing faulty bleed valves ensures brake fluid remains clean and free of air, keeping your braking system safe and reliable.
