Front Brake Caliper Piston is a 41mm piston that operates in the front brake caliper, part of the braking hydraulic circuit for solid disc brakes.

It sits within the caliper bore, where hydraulic pressure from the brake circuit acts on it to press the brake pad against the disc.

Frequently asked questions

What does the 606683 caliper piston do?

The 606683 is a front brake caliper piston. It sits in the front caliper bore and transfers hydraulic pressure from the brake circuit into mechanical force against the brake pads on the Defender, Discovery 1 and Range Rover Classic solid-disc front brakes.

How many caliper pistons are needed?

Typically four front caliper pistons are needed per vehicle, two per front caliper. They're sold individually, so order four to rebuild both front calipers, or two to do one side.

Which models does this front caliper piston fit?

This piston fits the solid-disc front calipers on the Defender up to 2016, Discovery 1 and Range Rover Classic. The Discovery 1 application runs to VIN WA799999 and the Range Rover Classic covers 1986-1994 builds. Confirm you have solid front discs, not vented.

Why do brake caliper pistons fail?

Caliper pistons usually fail through corrosion or pitting on the piston surface, which tears the seal and causes fluid leaks or a sticking brake. On these older Land Rover front calipers, seized pistons are a common cause of brake drag and uneven pad wear.
