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

Brand New units sold without an exchange
Porsche 911 1969 - 1972 E/S
Porsche 911 1973 - 1983 2.7L / 3.0L SC
This OE Match, brand-new rear M-type brake caliper is engineered to match the original fitment and braking performance used on classic Porsche 911 models from 1969–1983. Supplied as a new unit and sold outright, it requires no exchange or surcharge, making replacement straightforward.
Manufactured to OE-matching dimensions and specifications, this caliper restores correct pad clamping and consistent braking feel when the original unit has become worn, corroded, leaking, or prone to sticking. Being a new assembly, it eliminates the downtime and inconvenience associated with refurbished or exchange calipers.
The caliper converts hydraulic brake pressure into mechanical clamping force, pressing the brake pads against the disc to slow and stop the vehicle. A properly functioning caliper ensures even pad wear, stable braking response, and predictable pedal feel - especially important on older vehicles where age-related corrosion and seal deterioration are common.
A worn or failing caliper can lead to pulling under braking, uneven pad wear, overheating, fluid leaks, or a soft and inconsistent brake pedal. Replacing the caliper helps restore safe, reliable braking performance while protecting pads and rotors from damage caused by sticking pistons or uneven clamping force.
When to Replace:
• Brake fluid leaking around the caliper or piston seals
• Sticking caliper causing brake drag or excessive wheel heat
• Uneven brake pad wear between left and right sides
• Pulling under braking or inconsistent pedal feel
• Corrosion damage or seized bleed screws during servicing.

Porsche 911 1973 - 1983 2.7L / 3.0L SC
OE Match, brand-new rear “M-type” brake caliper made to match original fitment and braking performance on classic Porsche 911 models from 1969–1983. It’s sold outright (no exchange/surcharge required).
Built to OE-matching dimensions and specifications, it restores proper pad clamping and consistent braking feel when your original caliper is sticking, leaking, corroded, or worn internally. Supplied as a new unit, it avoids the downtime and core-return hassle of exchange calipers.
It converts hydraulic brake pressure into mechanical clamping force, pressing the pads onto the rotor to slow and stop the vehicle. A healthy caliper helps deliver even pad wear, stable braking response, and predictable pedal feel - especially important on older cars where original calipers may suffer from age-related corrosion and seal deterioration.
Function:
• Hydraulic-to-mechanical braking: Uses piston movement to clamp pads against the disc.
• Braking balance & stability: Supports even braking on the rear axle for controlled stops.
• Service-friendly replacement: New caliper unit simplifies restoration/maintenance without needing a core return.
A tired caliper can cause pulling under braking, uneven pad wear, overheating, leaks, or a soft/inconsistent pedal. Replacing the caliper helps restore safe, consistent braking performance and protects rotors and pads from damage caused by sticking pistons or uneven clamping.
When to replace :
• Brake fluid leak around the caliper/piston area
• Caliper sticking (wheel running hot, dragging brakes)
• Uneven pad wear side-to-side
• Pulling under braking or inconsistent pedal feel
• Corrosion damage or seized bleed screw issues during servicing
