Changing calipers Disk brake calipers self-change as the cushions wear out. The pistons will project marginally further as the general cushion width psychologists, and this can make it extremely hard to introduce the new cushions with their full thickness compound. By far most of the brakes are currently open systems, so you should tenderly push the pistons back into the caliper whenever you have taken out the old cushions.
You can utilize a tire switch if you are stressed over harming the piston — they are generally delicate, especially those with a little finding pin that is anything but difficult to snap off. You may find that you need the influence provided by a more extended device, however, so utilize an enormous, level edge screwdriver enclosed by thick cardboard or a ring wrench that sits conveniently on the substance of every piston.
Push one piston tenderly back into the caliper body until it sits flush, at that point rehash with the contrary piston. You may find that as you push in one piston, different moves out once more; drive forward with a couple of more cycles however on the off chance, the pistons won’t sit uniformly and flush with the caliper, you should drain.
Stage 1: If soil is allowed to stop behind the cushions, it can harm the piston seals, defile the brake liquid and cause air leaks. Before putting in, new cushions give the caliper body a decent perfect. Utilize a senior member cloth or tissue, with plain sudsy water — there should be no compelling reason to utilize a degreaser. Dodge solvents and brake liquid, as well, as these can harm the silicon piston seals.
Stage 2: Most cushions utilize a spring to spread the two faces separated when not squeezed to the rotor. Join this to the new cushions, ensuring you have both left and right cushions the correct path around. Abstaining from contacting the braking compound, press the two cushions together and ensure the spring is conveniently appended. Guarantee that the spring arms sit next to, not finished, the substance of the brake cushion.
Stage 3: Push the pair of new cushions into the opening in the caliper, turning around the move you made to eliminate the old pair. Push them in until they are solidly in the correct spot inside the caliper and any holding nail to the piston lines up with the cushion’s finding openings. At that point fit the holding pin, lastly the optional holding gadget, so the brake looks precisely as it was the point at which you began. Reattach the haggle the brake switch more than once to settle the pistons into place. At long last, bed in your cushions — see Brake Pads Must Be Changed.
