They are actually pretty simple, but check or replace the rotors before you install new pads. The front discs have 2 bolts per caliper as do the rears. There are hardware clips that are different on the front and rear.

You unbolt the caliper and tie it up with a rope or coat hanger so the caliper does not hang by the brake hose. Service the rotors and then when you are ready to replace the caliper, you take off the master cylinder cover. Then you use a "C" clamp to drive the caliper piston flush into the caliper. Doing this will force Brake fluid back into the Master cylinder. This is why the Master cylinder cap must be off. Attach the brake pads with a chemical to eliminate rattles and then slide the loaded caliper over the rotor. Attach the 2 bolts on the caliper and then you are ready to bleed the system.

Repeat this on each wheel and then bleed all 4 wheels. There will be very little air in the system using this method. The back brakes have the E-Brakes inside the rotors. If you pull off the rear rotors you will have to loosen the E-brakes by turning the Starwheel inside the rotor to allow for more clearance. Adjust the same Starwheels by tightening until independent wheel drags substantially, then loosen up 5 or more clicks on the Starwheel.

The calipers will take care of themselves and center themselves through use. Thats about all I can say about this process. I hope this helps you.

Is it ok to replaced rear Rotors with out replacing break pads?


OK if they are smooth and thick. It's not dangerous; it doesn't cause uneven braking, but I wouldn't advise putting very ridged pads back in - as they will tend to accelerate the wear on the disc/rotor. You CAN take the worst of the ridges out with a file, if you can use a file accurately and don't taper the pad... Don't use emery paper as some abrasive will remain in the pad and wear the disc/rotor. Also if the pads are very worn down, they will wear away quicker and could damage your new disc/rotor.

Front wheel bearings


first check the pads have not worn down to metal if they have the disc will have to be replaced , if the disc is in good condition and the pistons are free press them back into the cylinders and then the pads can removed .check the master cylinder does not over flow as the pistons are pushed back. Brake fluid is a paint remover. the wheel bearings don't have to be touched to replace pads. After new pads are fitted the brakes will have pumped to bring the pads out to the disc.

Squealing at the right front wheel


The brake lining's have worn away, the squealing was metal to metal (worn pad against metal disc) The worn pad will have damaged the brake disc. Very dangerous. You will now have to have new brake pads and discs fitted to BOTH front wheels to put it right. Good luck

I'm replacing the brake pads but don't have money for new discs right now. Is it ok to put on new pads for a couple of weeks and then new discs?


Disk's and pads are the same thing,Brake pads,Brake disk.
Are you meaning the rotor?
If you are the answer is yes,you don't have to replace the rotors unless you have a rotor brake vibration when you are applying the brakes on your car.
If you do want to change rotors later,you can but remember to take sand paper to the previous new pads,because they were used and got hot and hard they will now score the new rotors,that is why you sand the pads.

The hard part is pressing the caliper piston abck into the caliper so you can get the new, thicker pads over the rotor. A large C Clamp works best.
