Disc Cleaning...

How should I clean my discs before installing new pads?

I'd use brake cleaner and a Scotchbrite pad?

I use a rotor hone, remove the disc and put it on the table of my drill press and hone both sides of the blade. Does a perfect job.

Honestly, unless you're racing, it's not necessary. Just spray brake cleaner on a rag, wipe down the rotors and install the new pads.

All you care about is removing any residual grease from the maintenance itself. Most use a clean rag and brake cleaner.

There is no other cleaning maintenance required.

I wouldn't be honing the discs. They are not designed to be machined and are not thick enough to be removing material. If they don't meet spec, they are replaced.

Scrubbing in the new pads cleans the disc surface as much as they need to be.. Just wipe the brake dust off the other bits.
Has always worked for me.

Agreed...the new pads will clean any old junk off.
Now...if you got grease/oil on the rotors..BreakKleen works well. Just be carefull about getting it on the wheels or tires.

But any old pad residue..don't worry about it. This hasn't failed me since 1986 and over 650,000 miles ago.

Scotch brite pad and then brake cleaner. Clean out the calipers while you are in there with a toothbrush and soapy water. Especially around the pistons.

Actually rotor honing is what gets rid of pad residue, yes if your not racing it's not as important. But honing does the best job. Scotch brite pad on roloc disc is very good too.

Honing takes off next to nothing for blade material, just the hard pad deposits.
