Function and Purpose
This kit is essential for restoring rear brake caliper performance.
It helps to:
• Replace worn or corroded caliper pistons
• Restore hydraulic sealing within the caliper
• Maintain consistent braking pressure
• Ensure smooth piston movement
• Protect against contamination and moisture ingress
Why Replace Brake Pistons & Seals?
Brake components are exposed to heat, pressure, and environmental contaminants.
Common issues include:
• Brake fluid leaks
• Corroded or sticking pistons
• Reduced braking efficiency
• Uneven brake wear
• Damaged seals and dust caps
Replacing pistons and seals together restores braking performance and reliability.

DOT 4
Having an extremely high boiling point and lower viscosity than required, it meets and greatly exceeds regulatory standards. Also suitable for vehicles with ABS.
Vapour Lock formation
This sort of habit leaves room for the Vapour Lock, the formation of vapour bubbles due to boiling of the brake fluid that replace the normal fluid and are compressed, thereby sending the brake pedal to its fill stoke (spongy pedal). The origin is incident in the porosity of the tubes that make up the braking circuit, which in time draw moisture into the fluid, drastically reducing the boiling point. The result is a reduced braking efficiency.
Brembo Premium Brake Fluid
Brembo Premium brake fluids have a higher boiling point that exceeds the standard, thus offering superior resistance to the Vapour Lock and ensuring braking efficiency even at low temperatures. With high anti-corrosion properties and resistance to oxidation, Brembo brake fluid also allows for long-term unaltered chemical/physical characteristics of the fluid in operating circuit; therefore, preserving its integrity.
