Information
Brake caliper seal repair kit. REAR
Repair kit designed to rebuild the rear brake calipers of classic Porsche 911 models from the 1969–77. This kit includes all necessary sealing rings, dust boots and associated hardware required to restore proper hydraulic operation and sealing integrity of the “M-type” steel calipers.
Sold per caliper.
Porsche 911 1969-77 REAR.
"M" type The S calipers are aluminium and the M calipers are steel
• Position: Rear axle brake caliper assembly—used to rebuild one caliper (sold each).
• Applications: Ideal for use when calipers show signs of leakage, piston sticking, seal degradation or during full brake system overhaul/restoration.
Brake caliper seals and boots are crucial for maintaining hydraulic function, preventing fluid leaks and ensuring piston mobility. When seals wear out, you may experience brake drag, uneven pad wear, reduced stopping performance or fluid leakage. Replacing with a correctly specified kit ensures safe, consistent braking under all conditions.
When and why to replace:
• Visible brake fluid leakage around the caliper body or piston boot.
• Caliper pistons sticking or uneven pad wear.
• Brake overhaul where pistons are removed and seals are exposed.
• Restoration of vehicles where the original seal kit has not been replaced in decades.
