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
