Porsche Front Brake Caliper Seal Kit - M Type caliper
1 kit per caliper - 2 required per car

Restore the performance and reliability of your braking system with Front Brake Caliper Seal Kit, designed for Porsche 911 models equipped with M Type front brake calipers. This essential brake caliper rebuild kit contains the seals required to overhaul worn or ageing brake calipers, helping restore hydraulic efficiency and ensuring consistent braking performance.


Fits:

• Porsche 911 1965-1968 2.0L / 912 SWB (F)
• Porsche 911 1968-1973 2.2L / 2.4L / 2.7L RS LWB (F)
• Porsche 911 1974-1975 2.7L 

Brake caliper seals play a vital role in maintaining hydraulic pressure within the braking system. They prevent brake fluid leakage, protect internal caliper components from contamination and allow the caliper pistons to move correctly during braking. Over time, exposure to heat, moisture, brake fluid and age can cause seals to harden, crack or deteriorate, compromising braking performance and safety.

Replacing worn caliper seals is a key part of brake system maintenance and restoration, particularly on classic Porsche models where original components may have been in service for decades.

What Does a Brake Caliper Seal Kit Do?

A brake caliper seal kit provides the essential sealing components required to rebuild and restore brake calipers. The seals maintain hydraulic pressure behind the caliper pistons while also preventing dirt, moisture and contaminants from entering the caliper assembly.

Correctly functioning caliper seals help provide:

Reliable hydraulic pressure Consistent braking performance Smooth piston operation Protection against brake fluid leaks Reduced internal corrosion Improved caliper longevity

Without effective seals, brake fluid can escape and braking performance may be compromised.

Symptoms of Worn or Failing Brake Caliper Seals

Brake caliper seals naturally deteriorate over time due to age, heat cycles and exposure to brake fluid.

Common symptoms of worn caliper seals include:

Brake fluid leaks around the caliper Soft or spongy brake pedal Reduced braking performance Loss of hydraulic pressure Uneven brake pad wear Sticking or dragging brakes Contaminated brake components Visible cracking or deterioration of seals Corrosion around caliper pistons Increased stopping distances

In severe cases, seal failure can lead to significant fluid loss and reduced braking safety.

Why Brake Caliper Seal Replacement Matters

Replacing worn brake caliper seals helps restore braking system reliability and prevents more expensive caliper damage.

Benefits of replacing caliper seals include:

Restored hydraulic pressure Elimination of brake fluid leaks Improved braking performance Smoother piston movement Reduced brake drag Improved brake pedal feel Protection against corrosion and contamination Extended brake caliper service life

For classic Porsche 911 models, regular caliper maintenance is essential to maintain the precise braking characteristics and safety standards expected from the vehicle.
