brake job question

[knightbird123]

When retracting the calipers with a C-clamp, should I losen the screw to bleed the brakes while retracting them or not ?

This is my first time doing a front brake job. I want to install new crossdrilled/slotted rotors and ceramic pads. What is the difficulty of this job and what are some important things to know before doing this type of job?

NO!

Don't touch the bleeder screw. Just squeeze the piston in so you can get the pads on.

Difficulty: cakewalk. If you've done rear (drum) brakes than you'll have no problem.

I use the bleeder screw all the time when doing a brake job. You don't want all the contaminants going back into the system do you?

Yea, if you use the bleeder screw there's a chance you'll get air into the system but that's why you bleed the system afterwards. Better some air in the system than old contaminated fluid. This is especially true for cars with ABS. All the crud in the fluid can potentially mess up an ABS system.

Neva touch the bleeder valve until you bleed the brake system to get the air out.
There is no contaminated fluid in the calipers.
If your brake fluid is contaminated then the whole system is contaminated.
Just press the piston back wit a C-clamp.

what are all the tools needed to install the front disc brake pads and rotors?

What else is generally changed when doin a rotor/pad job?

What chemicals should I apply on the rotors or ceramic pads before installing them on the car?

What other brake components should be greased/lubricated or sanded down?

To compress the caliper cylinders easier make sure to pop the top off of the brake fluid reservoir first. Put a clean rag around or slightly in it to soak up the fluid that might spill back out when the fluid level rises during compression.

I know it's different practices and different methods, but someone want to explain WHY it's not a good idea to crack open the bleeder screw before resetting the piston?

I'm not saying one method is "better" over another but just curious why the method of leaving the bleeder screw closed is preferred.

You leave the bleeder screw closed because[b] you don't have to[/b] open the bleeder screw in order to reset the caliper piston. you only open that bleeder screw if you introduce air into the brake system by not having enough brake fluid,or changing the brake fluid, replacing brake lines, or troubleshooting. Maybe that should answer your question.

I guess that makes more sense if you put it that way as opposed to "loosening the bleeder screw is a bad idea" (no one has said this, it's just the impression I get). Still though, on an ABS equipped car, I wouldn't risk it. My personal opinion, crack it open anyway. It definitely does not hurt to do so and will only benefit you in the long run.
