Enjoin provided I Obligation Late Brake Calipers
Calipers are authentic conspicuous components in CD braking systems. Pistons expand from hydraulic impact on entail when the brake pedal in the vehicle is applied. The pistons squeeze the brake pads, which then contact the surface of the rotor and slow the vehicle down. When a caliper becomes malicious, there Testament be some in evidence telltale side tool. Identifying the symptoms Testament aid you pride the damaging Element and then alternate it.
Instructions
1. Clear the hood and test the fluid aligned of the proficient cylinder. A leaking piston, bleeder or brake hose Testament empty the reserve fluid from the adept cylinder eventually. Provided crucial, top the master cylinder off with Disinfected brake fluid.
2. Assessment propel the vehicle to start diagnosing the calipers. Choose a parking collection or low-traffic course whether practicable. Before beguiling off, be firm you accept a undeniable brake pedal. Whether the brake pedal fades to the floor with a beggared braking response, accomplish not comp manage the vehicle.
3. Before beginning, place you bare hand near each wheel that employs calipers. Do not touch the wheel because a stuck piston will heat the brakes and nearby components up severely and you could burn your hand. Burning brakes will give off both intense heat and a pungent burning odor. If a wheel is indeed extremely hot, allow it to cool down before proceeding.
4. Operate the vehicle for Ten to Fifteen minutes applying the brakes recurrently. Bring the vehicle back to the nature where you method on disassembling it for besides diagnosis. Bring the vehicle up to Thirty mph and then employ the brakes firmly. Conclude if the vehicle pulls to the conscientious or the left when the brakes are applied. This would be a useful letter that a caliper piston is sticking and apart one side of the brakes are working properly.
5. Lift the axle of the vehicle that contains the suspect caliper. Use the jack to lift it and be sure to place it safely onto jack stands.
6. Remove the wheel using a lug wrench to remove the wheel nuts.
7. Remove the two caliper guide bolts using a ratchet and a suitable socket.
8. Pry the caliper off of the rotor with a small pry bar. Some calipers will contain pads attached to the caliper while others will leave the pads behind in the caliper anchor.
9. Inspect the caliper for any visible signs of fluid leaks. Leaking brake fluid will be very obvious. Thoroughly inspect the piston area, the bleeder screw and the brake hose connection. Also inspect the rubber protective boot surrounding the pistons. Tears or rips in the boot will not necessarily mean the caliper is defective, but it will compromise the pistons eventually. While you're at it, inspect the brake hose for any visible signs of cracking or rips in the rubber.
10. Hang the caliper to the suspension using a caliper hook or a wire hanger. Compress the piston using a C-clamp or a caliper piston reset tool. Some rear disc-brake calipers will require the reset tool to screw the piston into the bore while most all front calipers will require compressing the piston into the bore with a C-clamp. Compress it slowly. If the piston does not bottom out in the bore or resists compression, the piston is bad and the caliper needs to be rebuilt or replaced.
