Changing NON- Anti lock disk brake pads

Does the car have anti-lock brakes. I will cover anti lock brakes later, but it is very crucial that you do not use this method on anti-lock brakes!



Some it is okay on, and others it will destroy the processor on....So here we go



There are usually two bolts that hold the caliper on the hub assembly



1. Crack loose the lug nuts, then raise the car and remove the wheel.



2 .Remove the two bolts holding the caliper to the hub assembly and pry the top of the caliper off the rotor, This will require a forward motion, as they pry off towards the front of the car, not the side.





3. After removing the pad closest to you, you can either use a C- clamp, or an actual caliper compression tool. Leaving the pad on the actual caliper piston, you then screw the bolt in a tighten direction to push the piston back into the caliper.




4.  This action pushes the fluid back into the master cylinder and creates enough space in the caliper for the new brake pads.




5. Remove the C-clamp/ caliper compressor, and remove the used pad.



6. On most cars the rotors should wiggle right off, and you should take them in to be resurfaced. As the brakes wear on the rotors, they make them as slick as glass. Having them turned will increase the friction available when the brakes are applied, and push the caliper back when in the rest position, assisting in the lowering of brake noise




7. Purchase anti squeak glue when you buy your pads. Although you have to change organic pads more often, they are much kinder and gentler to your rotors.  Apply the anti squeak to the caliper piston and the back side of the outer pad. This will keep the pad attached to the caliper and resist the chances of chatter and squeaks



8. Roll the caliper back around the rotor, with the pads propperly around the rotor.



9. jostle it around so that the two bolts line back up to their original location and tighten them down well.



10. If you look closely, the bolts are actually slides for the caliper to slide on...Make sure they are clean enough to do their job.



11. All clips and or pins that were in should be placed back as you are rolling the caliper in place!



Special notes


When one side is excessively worn, it is very possible one of the calipers has a sticky spot and may wear fast



deep groves in rotors will cause them to be too thin, and quality machine shops will not turn them beyond their minimum thickness



The passenger side will be a mirrior image of the drivers side, so assembly will seem backwards



Soft brake hoses will over expand under pressure and cause weak, spongy brakes
