Brake calipers rear and front for car

The parts of the first type have a simple and compact design. They are installed on budget cars with low-power engines. These products are inexpensive and easy in maintenance. However, they are not suitable for aggressive driving style. Apart from this, their inner brake pad breaks down faster than the outer one as it activates sooner.

The fixed components are installed on heavy SUVs and performance sports cars. They are not prone to quick overheating and have a reliable design. On the other hand, such parts are expensive and their maintenance cost is higher.

To do this job, you will need:

• a car lifting device;
• wheel chocks;
• a set of ring spanners;
• a flat and Phillips screwdrivers;
• a piston rewind tool;
• pliers;
• brake fluid of the manufacturer’s recommended type;
• a container with a pipe for waste fluid.

The procedure depends on the vehicle make and the axle where the part is mounted. You can find a detailed instruction in your vehicle’s workshop manual. Generally, it consists of the following steps:

1. Park the car on an even surface.
2. Apply the parking brake.
3. Put wheel chocks under the wheels and loosen their bolts.
4. Open the bonnet and unscrew the cap of the brake fluid tank.
5. Raise the car and unscrew the wheel bolts.
6. Remove the wheel.
7. Press the pistons into the caliper.
8. Disconnect the brake hose.
9. Pull the brake pads away from the disc.
10. Unscrew the caliper fasteners and remove it from the steering knuckle.

Warning! Never apply the parking brake before removing the components on the rear axle.

There are two main types of the products used for lubricating the parts: spray and paste. They retain their working properties even at high temperatures and being exposed to moisture and service fluids. Usually, they are based on oil with addition of metal particles. The lubricants can be divided into 3 main types:

• High-temperature anti-seize. They can be copper, based on molybdenum disulphide, or have a complex formula. They are used for lubricating the guide pins. Never apply these products on the working surfaces of brake pads. This type is represented by the products from Liqui Moly, Mannol, Textar, and other brands.
• Mineral. They contain bentonite and fatty acids. These products are designed for cars used in urban conditions. This type of lubricants are produced, for instance, by the Teroson brand.
• Synthetic. These greases contain a set of oxidation inhibitors and wear-preventive additives. They retain their working properties within a wide temperature range: from −40 to +300°С. They are suitable for treatment of all moving parts. You can find them in the product catalogues of Permatex and TRW.
