Really hot rear brake disc

could be described as a throbbing perhaps

or "Flexing"....

Well what ever it is, I don't think the disc is warped yet, jus that it is hot and might warp soon! I am going to go outside and take the caliper off, see if I can see anything...

fixed! I think

I dismantled eventually using cruddy work tools, and found that (bear with me as I don't know the right names for things!) the little thin metal assmbly that sits behind the pads, kind of springy, had gotten mashed when the new pads were put in, so half of was bent in sticking between the pads. This was then rubbing against the top of the brake disc, so much so it had worn a shiny disc-sized groove into it. This was then superheating the disc and making my pads go a rainbow colour. I took it out, straightened it with some pliers and put it back in behind the discs. It seems well out of the way now, but when I tested it up and down the car park, I was braking heavily, making my rear wheel skid, and so when I felt it it was hot again . Now I just have to let them cool down, then ride normally and hopefully it will be fine. Rear wheel spins fine again now too.

Question: Do I ring up the mechanic in question and bollock him or ask for a discount?? It was an honest unlucky mistake, but we were spinning it and both heard the metal noise at first...

brakes will get very hot when you use them, jump off the bike after a gentle ride and spit on your finger then quickly touch the disc, it'll probably boil and hiss because the disc is so hot. sounds like you found the cause

Call them and at least give em a b0ll0cking, then ask for a discount

Sean C had a similar thing with his front pads on his last fateful rideout. Mechanic there had assembled one of the fronts wrongly. Luckily Tilt sorted that out for him. Make you wonder about these "mechanics" sometimes.

Definatly; there was a guy at uni with a bandit who had his bike serviced, and the mechanic hadnt torqued up the rear caliper bolt correctly. It had vibrated loose, then the whole caliper was flapping about on the wheel.

I only let my dad fix my bike, and I am trying to learn as much as I can to be able to do it myself - I think possibly I could trust a few of you lot on here aswell. I find it very hard to trust anyone with fixing something on my bike which, if it isnt done properly, could result in an accident and my injury.

According to this it is number 4 part the ".spring, pad" on the rear caliper that was mangled.

Well I try and do most stuff myself, but as he was changing the tyre, he noticed the pads were gone so I thought lets just bung new ones in as I have an MOT booked tomorrow morning. Just thought he would do it right!

Na, I'm not questioning you for a second I would expect someone to do it properly too, and not only that, to investigate any abnormalities after doing something...like metal-on-metal noises
