Brake calipers require periodic maintenance just like the rest of your braking system. The number one problem with brake calipers is caused by rust. The caliper and the internal piston are made from cast iron and is prone to rust just like any other ferrous material. Not replacing your brake fluid regularly will lead to water entering or forming in the system and that will rust the calipers and hard brake lines from the inside out. A rusted caliper will cause the piston to seize, creating a stuck caliper, dragging brakes, wheel vibrations, pulling to one side, excessive brake dust and heat, or even a total loss of brake function on that wheel.

We offer brake caliper rebuild kits but sometimes the condition of the inner piston is just not safe to re-use. Unfortunately you really don't know for sure until you have removed the caliper and taken it apart. As a convenience we offer freshly rebuilt calipers. Each caliper is cleaned and sand-blasted to remove surface rust and dirt/grime. The pistons are rebuilt with new seals and dust boots and re-installed into the caliper housing. The caliper you get is ready for a direct replacement on your car! There's no mess from brake fluid leaking everywhere and no fighting to get the piston seals to fit. Replacing the calipers with newly rebuilt units does not take any more signifcant time during a typical brake pad/rotor overhaul. Rebuilt calipers are sold on a core exchange basis so we need your original calipers returned to us.

This caliper bushing kit will eliminate flex caused by weak rubber caliper bushings. As the brake pedal is pressed the caliper grabs the rotor and twists on its mounting bushings. The rubber bushings allow the caliper to deflect and twist which affects pedal feel and results in uneven pad wear. These solid brass bushings will not twist or deflect so your calipers can squeeze the pads evenly on both sides of the rotor (sort of like what multi-piston big brakes do). This will give you much longer pad life and a more consistent pedal feel. This is the most complete kit we have ever sold with stainless steel caliper slide bolts, o-rings, and new dust boots. Unlike other kits, these bushings are pressed into the caliper and will not shift or slide on their own.

Installation is straightforward: remove the old rubber bushings and press in the new brass bushings (we recommend special tool 003326ECS03). High temp caliper grease or anti-seize is required. The new bushings include an inner o-ring that helps trap grease on the slide bolt, reducing friction and wear.

For most models with floating calipers. Fits the rear of E90/2 and E60, but for the front you'll need the kit found here. Does not fit E30 models with Girling calipers, but is compatible with Ate calipers.

The caliper sliding bolts are one of the most overlooked wear items in your braking system. Subjected to constant motion and often without adequate lubrication the guide bolts see a lot of wear and tear. Factory BMW caliper guide bolts are very expensive from the dealer - these 304 stainless steel bolts are less than half the price and provide outstanding resistance to corrosion and wear. They are manufacturered with tighter tolerances than the factory bolts too.

Price is per bolt unless noted (2 required per caliper).
