Brake Caliper REAR Porsche 911 3.2L 1984-89 91135242500, 91135242600

Brake caliper REAR. 
These are direct replacement calipers for the rear left (part number 91135242500) or rear right (part number 91135242600) side of a mid-1980s Porsche 911. They are manufactured to the dimensions, fitment, and technical specifications of the original. Replacing these calipers restores the correct brake pressure, pad alignment, and brake disc-to-rear wheel contact, restoring braking balance and safety.


Porsche 911 1984 - 1989

Brake calipers are crucial for safe, controlled stopping. Over time, calipers can suffer from corrosion, seized or sticking pistons, worn seals, fluid leakage or uneven pad wear. Especially on aging cars, the rear calipers may lose proper clamping force, causing longer stopping distances, uneven braking, noise or poor pad life.

Replace these calipers when you notice:
• Brake fluid leakage around the caliper body or piston area
• Uneven or rapid pad wear on the rear wheel
• Reduced braking performance, dragging wheel or vibration
• Maintenance/restore of the braking system during a rebuild

Installing a correct-fit caliper restores proper braking clamp, pad and rotor alignment and ensures your classic Porsche retains its intended braking performance and safety.
