Washing a rotor in water will not remove grease and oil, only metal particles missed my the machine shop. Gease and oil repel water. Hint: the WD in WD-40 stands for "Water Displacement Forumla 40." They make this fabulous product called 'Brake Cleaner' that displaces water and will lift off grease, fingerprints, and brake fluid from a rotor.

Dawn (in my post) does an excellent job of removing grease and other crap.

As to the manual it is the only one I have here at work. I have dozens at home and will gladly upload more to show you can indeed clean hardware with fluid.

Nobody's questioning whether you can clean calipers and pistons and seals and pins with brake fluid. But you DO NOT clean rotors and pads with brake fluid... that's idiotic.

I don't.
Edit: and I didn't mean to suggest that you do.

Bah... just use some good synthetic oil to clean the rotors... make sure to soak the pads in it overnight too. :roll: (if you didn't catch on... that was a joke... don't do that)

Brake clean is like $3 a can and is more than enough for a complete brake job... get it, do it right.

Also compress the caliper piston(s) BEFORE putting the new rotor on. If you don't, chances are you won't get the caliper, even with the old pads, onto the rotor and you'll end up rigging something up to compress the piston with the caliper in your hand. Also check the brake fluid level... if it's been topped off, take some out with a turkey baster type thing otherwise you'll have brake fluid overflowing all over the place when you compress the caliper piston... and brake fluid cleans paint off metal very well.

Rotors are washed. Brake Hardware is cleaned with fluid. No need for brake clean. Also the caliper will be flipped up and it will be very easy to compress the piston with a c-clamp.

You're right... OP... save $3 on your $80 brake job and half ass it.

How is that halfass? The same thing is accomplished.

No... it's not... brake clean cleans petroleum products off the surface AND completely evaporates. Nothing else does that except alcohol, and brake clean is much more effective.

I've been cleaning rotors with soap (dawn) and water for years. The brake harware can use the coating.

I didn't see this before... the brake hardware can use the coating? WHAT coating? You don't want ANYTHING left on the rotors or pads... that's the whole reason brake clean was invented and is used.

*EDIT* I don't mean to be a dick, cause I think your intentions are in the right place here... I just think you're giving some unclear advance and maybe don't fully understand the process and WHY certain steps in the process are even done.

Brake hardware is not pads/ rotors. Walk into Napa and tell them you need the brake hardware for your car. They will not give you pads and rotors. They will give you shims/ springs/ retainers.

You should use soapy water though, not just plain water, since soap will lift those metal particles and hold them in suspension until you wash them away with water.

Absolutely. Soap will also remove most of the machining oil off of the part, and break up any green sand from a rough casting, expecialy if hot-tanked. Granted rotors are usually cut dry, but using soapy water to clean almost all machined parts is generally part of the plan.

I think you misquoted... but again I will say... WHAT coating? You actually think any residue from Dawn is going to stay on those parts? Haven't you ever seen steam coming from wheels on cars on a rainy day? That's because the brakes get so hot the water boils instantly when it comes in contact with the rotor or caliper.

Actually rotors are cut with a light machine oil flowing over them to cool the cutting bit... otherwise the bit will chatter and your rotor is pretty much trashed. Yes... OIL... yet another reason to clean with brake clean.

*EDIT* Well... not always... but we had one GOOD machine at college that used a light oil... other ones didn't and worked ok... but would chatter if you got to aggressive with the amount of material you were taking off, even with a silencer band on the rotor.

You're using the guys working the parts counter at NAPA as some sort of authority figure? Ok... I'm done in this thread... I've made my point.

I should've figured an argument would've broken out on ATOT...

Jeff and/or Evadman, can either of you contact me on AIM at alexjohnson16?

RE: if you use another service, I can look you up...

Jesus wtf? I'm working and explaining is getting annoying. Iwas reffering to the hardware cleaned with fluid.

You haven't made any point other than you seem to get confused by correct terminology.
What should I call it. All these parts suppliers seem to have it wrong.
