*URGENT* disc brake help

so my disc brakes are working realy shit… first they were squeking so this guy took off my disc sanded it a bit and whatever, then he told me to put some degreaser on it so i did. now its working really shit, it wont stop me at all. im thinking it could be the pads but i dunno. can you tel me what i can do to the disc and the pads to make them better. oh btw they are mechs. and no dont say upgrade to hydraulic or anything like that. just something like baking or sanding or somehting i dont know….

try your pads from your back or front disc brakes..

if they are not hydro's then you should start by replacing cables. Then I would wipe down the rotor's with rubbing alcohol. If these things don't fix your brakes then I would replace the pads.

If this problem continues then you know you need hydro's

Sounds like the last thing you did ,the degreaser didnt do the pads any good,maybe you need to wear the pads in again after the degreaser?

You could try baking/sanding the pads followed by some stops to break them in.

Try new pads if that doesnt work

ya, your pads are definitely toast, degreaser leaves a residue and pads are like metal sponges. there may still be something on your rotor too, the rubbing alchohol may do the trick for that, and you can always rinse them too in some water. I'm not sure the degreaser will come out of the pads with cooking, but i suppose it's worth a try.

i just tried sanding them and some rubbing alcohol and they are still working shit, i swapped the fronts for the back. i think im just going to go replace them

on the inside of the caliper (the side facing you wheel)you should have a little round adjuster thing, give it a few turns and it should move your pads closer together, make sure you loosen off you cable first. if you dont its not going to help you because there is a stopper thing on it and thats whats probly keeping your brakes from working. i had the exact same problem with my mechs. hopefully that made sence

no its not that my brakes are set perfectly. its just that its as if there is something like soap on it and ive tried everything to take it off

rubbing alcholo the rotor and pads. if still no worky put em into the oven till they stop smookin at liek 375

You don't need to put pads in the oven.

I use a stove and it works perfect all the time (backside on the stove). After cooking it, give it a wipedown with some isopropyl (rubbing) alcohol. Let dry. Then give the rotors a wipedown with alcohol as well. Let dry.

After that, find a nice, big, hill. And start burning them in again. :)

or a BBQ :P

Pfft,

Flatulence + Lighter = nice pads

jsut boil the pads and they should be good as new

After that, find a nice, big, hill. And start burning them in again. :)

This is important, as after you've properly degreased your pads they need to be broken in.
