What Does a Brake Caliper Overhaul Kit Do?

Over time, the seals, dust boots and service components inside the brake calipers deteriorate due to heat, age and repeated braking cycles. A caliper overhaul kit restores the internal sealing and protection of the caliper, allowing the pistons to operate smoothly and maintain consistent hydraulic pressure.

The overhaul restores:

• Correct piston sealing.
• Smooth piston movement.
• Protection against water and dirt ingress.
• Proper brake pad operation.
• Reliable hydraulic performance.
• Consistent braking performance.
• Long-term caliper reliability.

A professionally rebuilt caliper can often provide many more years of dependable service.

Why Do Brake Calipers Require Overhauling?

Brake calipers operate in one of the harshest environments on the vehicle. Common causes of wear include:

• Heat generated during braking.
• Ageing and hardening of rubber piston seals.
• Dust boot deterioration.
• Moisture entering the caliper.
• Corrosion around the pistons.
• Contaminated brake fluid.
• Sticking pistons.
• Seized bleed nipples.
• General wear after high mileage.

Ignoring worn seals can eventually result in sticking brakes, uneven pad wear or brake fluid leaks.

When Should a Brake Caliper Be Rebuilt?

A caliper overhaul is recommended whenever:

• Brake pistons become stiff or seize.
• Dust boots split or perish.
• Brake fluid leaks develop.
• Uneven brake pad wear is evident.
• The calipers are removed for restoration.
• During a complete brake system refurbishment.
• The vehicle is being prepared for fast road or track use.
• As preventative maintenance on ageing vehicles.

Rebuilding both front calipers at the same time ensures balanced braking performance across the axle.
