![]() Loosen the lower caliper slider pin bolts.Using a Torque wrench, torque the bolts to the manufacturer’s specifications.The caliper bolts have a torque spec of 45 ft/lbs. Torque these bolts to specification. The front brake caliper bracket typically requires to be tightened to 80 ft/lbs. Fasten the retaining bolts using a ratchet.Once it fits, install the upper and lower bolt initially by hand.Test fit the new brake caliper assembly against the bracket.Secure the caliper without stretching the hose.Pull out the brake caliper assembly, and be wary of the flexible brake hose.Remove the bracket’s lower and upper retaining bolts using a ratchet with a 16mm socket.Loosen the retaining bolts for the caliper bracket using a breaker bar and a 1/2 inch socket.With a flat-head screwdriver as a lever, create some space between the caliper and rotor.Place a catch pan below the brake caliper to prevent brake fluid from escaping to the environment.Once the wheel is free from the studs, lift it and set it aside.Remove the lug nuts and use the lug nut wrench to lift the wheel while your other hand lifts the wheel from the top. ![]() Place the jack below the body frame and raise the car until the wheel can be turned freely by hand.Do not remove the lug nuts completely removing the lug nuts at this time would cause the tire to fall prematurely, which may cause an injury. Using a lug nut wrench, loosen the lug nuts of the affected wheel by directing your torque counterclockwise.Park the vehicle on level ground and set the parking brakes on.Grinding / rubbing noise that is constant and does not go away unless you apply the brakes.Abnormal noise when in motion and /or when braking.A seized brake caliper or caliper slider can cause the vehicle to pull to one side. Always flush the brakes to get rid of the old fluid, and bleed all of the lines to get rid of any trapped air that could cause a soft pedal.Common symptoms of a bad brake caliper include Other items that may be needed when replacing calipers include new brake hoses (replace if leaking, cracked, brittle or worn), and certainly brake fluid. Mismatches side-to-side may cause uneven braking. But if only one caliper needs to be replaced because of a leak or problem, the replacement caliper should have the same type of piston (steel or phenolic) as the one on the opposite side, as well as the same type of friction material (nonasbestos organic or semi-metallic). If you find uneven pad wear between the inner and outer disc brake pads, it’s a sure indication the caliper (or caliper piston) is sticking.Ĭalipers should usually be replaced in pairs, especially on high-mileage vehicles. The uneven braking that results may produce a hard pull toward the “good” side when the brakes are applied, and/or a steering pull toward the “bad” side when the brakes are released. When a piston sticks, one of two things can happen: the brake may not apply or it may not release. But both fixed and floating calipers alike can sometimes “freeze up” or lock if a piston becomes jammed or stuck in its bore due to corrosion or swelling. Fixed calipers don’t suffer from this type of problem because the position of the caliper is fixed and the caliper does not move. This may cause increased wear on the outer pad as well as a steering pull to one side because of the constant drag. A “sticky” or “frozen” caliper may also cause the brakes to drag if the caliper does not slide so the outer pad can kick away from the rotor. If the slides or bushings on a floating caliper are rusty, worn or damaged, the caliper may not move freely causing the pads to wear unevenly.
