Rear Brake Caliper Seal Kit for Subaru

This rear caliper seal kit is a small but critical service part that keeps your braking system tight, clean, and safe ✅. It is needed whenever the rear caliper is rebuilt, when you notice fluid seepage, or after years of heat and road salt that harden rubber.

Why you need it

The kit restores the hydraulic seal around the caliper piston and renews the dust protection. Fresh seals help maintain correct brake pressure and smooth piston movement, improving pedal feel and rear brake balance.

How it works

The inner piston seal holds brake fluid under high pressure and slightly “rolls” as the piston moves, allowing the pads to clamp and then retract a hair when you release the pedal. The outer dust seal blocks water, grit, and corrosion from reaching the piston surface ️.

What happens if it’s worn or broken

Cracked seals can cause fluid leaks, a soft pedal, uneven braking, dragging pads, overheating, and premature rotor wear. In severe cases, contamination and rust can seize the caliper, reducing stopping power and risking brake failure ⚠️.

Best practice

Inspect the piston and bore, use correct brake grease, and bleed the system after installation for reliable results.
