Rear brake disc question
« on: June 11, 2019, 01:51:53 am »
Seems my rear brake disc picked up the nasty habit of rusting this winter. Now rust between rides. Will be changing rear pads at end of season. Would prefer not to use them as a de-ruster in the future rides.

What about wiping disc with a paint etch so as to change the rust's composition? Other more sound thoughts? I like the ride more frequently, faster and  brake more solution. But somehow other aspects of life are in the way.

pull the disc, and take a rubber sanding block and some 80 - 100 grit Emory paper to it, and manually scrub it all off... then clean it with BrakeKleen spray. you can do the same to the pads, place the sandpaper on a flat surface, and scrub the friction surfaces.. and spray them also.

easy cheap fix...
I wouldn't use any "rust removing paint preps" to do what can be done manually, just adds possibility of contamination in some manner, if the wrong stuff is used, or not cleaned properly afterwards.

First check and make sure the disk is with in the service limits.
No point in fixing the problem on an out of limit part.

Yes all in spec. 180 grit seemed to knock in down with little effort to clean metal. Did not take long. Will watch carefully to make sure it does not return between rides down here in Louisiana. A land where mold and rust are kiss'n cousins...........
