The only time my brakes rattled was when a retaining clip on the brake pad broke letting the pad rattle around. I pulled the tire and wheel off, replaced the one retaining clip on the one pad and replaced the wheel and tire.
There are generally three types of clips that attach to or contact with brake pads. 1) Wear sensor: This is a small piece of metal which will touch the rotor and cause a squeal noise when your pads need to be replaced. 2) Pistons Clip: This clip is usually riveted to the steel back of a brake pad and it fits into the piston(s) for the caliper. This helps pull the pad away fromt he brake rotor when not applying the brakes. 3) Pad Retraction Clips: These are many different types and designs, but generally they hold the pads away from the rotor when the brake is not applied. This is mainly to prevent cyclical rotor wear which will end up producing "Brake Judder" and pulsation of the brakeing system when stopping. Real annoying!
Brake pad changing is important in maintaining a car. A person lifts the car, removes the tire, brake shoe and old brake pad. Next put the new brake pad , put the brake shoe and tire back in their place, and lower the car.
These wires are normally for the Brake Pad Wear Sensors which tell the ECU ( or Brain !) that the brake pads are worn low and need replacing. I would say VERY important !!!!
take the motor off the backside of the calliper and turn the screw in with a allen wrench then push the piston in
How do you change brake pad on s60
The brake pad wear sensor is on the brake pads. On my 318ti, the sensor is on the left side, on the inboard pad.
Carefully pry pad wear sensor from brake pad. Then insert brake pad wear sensor into cutout in new pad where applicable.
It is recommended that you use the manufactory's brakes if you are doing this yourself. For each brake pad: To begin with, loosen the nuts on the tire, jack the car, then remove the tire. Remove the pins holding the caliper. The caliper now moves easily, and after inspecting the brake pads to see if they do need to be replaced you can just slide the pad out. Replace the clip then the brake pad. Push the pistons in so the new brake pad will go into place smoothly. Slide the caliper back down and replace the wheel.
A brake pad is the friction surface, replaced as it wears, between the caliper and the rotor.
After your brake pads have been replaced, scroll to the brake pad life display. On the brake pad life display hold the scroll button in until the brake pad life goes to 100 percent.
It is important to know how to change a cars brake pads. Lift the car, remove the tire, brake shoe and pull the brake pad out of the brake shoe/caliper.
