Rear Brake Caliper Seal Kit for overhauling the inboard-mounted rear brake calipers.

The kit supplies the hydraulic seals needed to reseal a rear caliper during service, restoring the seal between the piston and the caliper bore and preventing fluid loss at the caliper. It is fitted when rebuilding the rear calipers as part of the inboard rear braking assembly.

The rear calipers on these applications are inboard-mounted at the final drive rather than at the wheel, and are serviced as an axle pair.

Frequently asked questions

What is the AAU3380 rear brake caliper seal kit for?
The AAU3380 seal kit supplies the hydraulic seals to overhaul a rear brake caliper. It reseals the piston-to-bore joint, restoring the seal and stopping fluid loss at the caliper. On these applications the rear calipers are inboard-mounted at the final drive rather than at the wheel.
Which vehicles does this rear caliper seal kit fit?
This rear caliper seal kit fits the Jaguar XJ6 Series 2/3, XJ12 Series 2/3 and XJS. It's a TRW OEM kit matching Land Rover part number AAU3380. These models share the inboard rear brake caliper design.
How many kits are needed for a full rear brake overhaul?
You'll typically need two kits to overhaul the rear brakes, since the inboard rear calipers are serviced as an axle pair. Rebuilding just one side isn't usually advised, because braking should stay balanced across the axle.
Why do rear caliper seals fail and when should they be replaced?
Rear caliper seals typically fail as the rubber hardens and perishes with age and heat, causing fluid weep, sticking pistons or a spongy pedal. On the inboard rear calipers they're usually resealed once leakage or drag appears. Consult your vehicle's service schedule for inspection timing.
