BMW Brakes & Brake Parts for BMW 3 Series E46 (1999-2005)

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. 

These 2-piece floating rotors help dissipate heat better than a standard cast iron rotor and are also lighter for less unsprung weight. Managing heat in the brake system is vital to braking performance, especially on the track or when driven hard. It's why your brake rotors have internal vanes that vent heat as the rotor spins. These 2-piece ECS rotors feature an outer cast iron friction surface ring that is separate from the aluminum center hat. This allows better airflow through the vanes and for the friction ring can expand as it gets hot. The rotors are also cross-drilled for better ventilation and slotted to improve brake pad performance.

ECS 2-Piece Rotors feature:

• Aluminum hats for light weight
• Heat-treated cast iron friction rings
• 2-piece assembly improves brake cooling
• Anti-corrosion coating on non-friction surfaces and hard anodizing on rotor hat

These are the same size as the stock rotors so your stock caliper and mounting bracket will fit and there will be no clearance issues with your wheels or to other components. Stainless steel rotor retaining screws are included. You can use these with any brake pad.

Price is for the pair of brake rotors.

This item fits the following BMWs:
2001-2006 E46 BMW M3 with CSL or ZCP brakes
2006-2008 E85 E86 BMW Z4 M Coupe Z4 M Roadster

Brake pad wear sensors are a convenient part of the braking system, notifying the driver of when the material on the brake pads are getting low and need to be serviced. Unfortunately it is common in custom or upgraded braking systems that the pad wear sensor is non-existent or does not mate properly with the connector on your vehicle, leaving you with a brake pad wear warning every time you start your vehicle.

ECS Tuning has developed this direct-fit Brake Pad Wear Sensor Bypass to alleviate this issue. This sensor bypass will trick the vehicle's electronics into thinking that the brake pads have adequate pad material to keep the dashboard warning from appearing. No more unnecessary warnings when installing a big brake kit or your own custom setup. This bypass is a plug-and-play component that requires no modifications so you can revert back to your OEM setup if necessary.

Some vehicles may be equipped with two front brake pad wear sensors, or a front and rear sensor, please be sure to double check the required quantity for your vehicle before placing an order.

*During installation, make sure to clean the mated female connector on your vehicle of any dirt or debris to ensure that the Brake Pad Wear Sensor Bypass is engaged securely.
