Cleaning rotors.

Contaminated rotors – Am I right in thinking that wiping them with a meths covered J cloth will do the job?

Meths can leave a residue. (Apparently).
Isoprpoyly Alcohol is better.
I’d pop the pads out & give them a few swirls on some emery cloth also.

try Wynns brake and clutch cleaner out of Halfords.

its £6 or around that.

Pads are written off, shall be installing new ones. Imma give it a go with meths, see what happens.

Just a can of normal clutch and brake cleaner. Designed for the job.

Are you sure the pads are written off?

Pour boiling water on the pads in a dish and most of the oil will heat and float off. Then once dry emery board or similar. Worked for me!

Might give that a try actually, see what happens. Cheers.

I’m trying to ‘ghetto’ clean this btw, incase it ever happens on tour.

Hot water and washing up liquid will get them as clean as the fancy solvents, but is no good for pads.

The contamination is a thin oily film, just like greasy plates or pans, W-up liquid will get it off and rinse away easily and cheaply.

I recently bled my brakes with the pads in, which led to two sets of soaking oily pads. I set them on fire over the hob and then sanded them. Have been using them since without incident.

Oooh, interesting.

A quick sprint along the street and slam the brakes on test and the brake seems to be working OK.

Meths and boiling water. Hmm…

Works for me, I pop them in a pan and simmer for a while, sand off and they’re 9/10 times working as before. For rotors, just meths and a clean cloth, then lots of hot water to rinse.

Place pads face downwards on electric hob, leave for a minurte at most, lift off with pliers, theyre very hot and allow to cool on plate, not on worktop.

Some people forget these 2 points.

oh and there is a bit of smoke as the oil burns off and a bad smell.

Scrub with meths and an old toothbrush always seems to do the job. Remember to rinse with a bit of water as well, no point in dissolving (as in solvent) the oil that is contaminating, then just leaving some of it there.

Repeat a couple of times. I always find you have to re-do the burning in process in part afterwards, to key the rotors back into the pads.

Lasers, nothing else will do.

muddy ride will sort it

Muc off brake cleaner has always worked for me..
I’ve had shimano oil over a brand new RT86 rotor..covered it in muc off brake cleaner and let it soak for a bit, then wiped it all off..
No probs at all..

Hot water / fairy liquid on the rotor

Hot water on the pads then burn off the remainder on the hob. May take two goes but did it on an old set of hayes 9 once when I didn’t have time to go get new pads. Worked really well and has been fine since

Ebay. Medical grade isopropyl alcohol wipes. 100s of them for around £2. Work a dream. Really small, weigh nothing and are individually packed so you can easily take a couple with you.

Worth noting that after a clean the brakes will take a mslla amount of time to get back to full power. I think the “science” behind this is that they are more effective when some pad material is deposited on the rotors

Medical grade isopropyl alcohol wipes.

Good for cleaning wounds too!

Automotive brake cleaner is the best and cheaper than cycling specific

A place local to me does a litre isoprop for £2.50 so that’s what I use.

Meths can have crap in it sometimes so I prefer IPA. I have mixed results fixing pads by baking them….

IPA = India Pale Ale, no? Sounds good to me… Hic! 8)

Fire and pliers, nothing else will do.
