front rotters

#1 Post by joecrx » Mon May 02, 2011 5:20 pm

i fitted second hand rotors to my bike ,wich seem to be working fine , so i was was interested how i warped the first set ,
now without going to tecknobububle .... i have noticed this ,
under light riding round the town ( going to shops etc ) when i park up several times now i felt the heat on my rotors , i have noticed the right rotor is always alot hotter to the touch than the left , is this normal ? they do both get hot after a good breaking though , but just light riding i feel the right rottor is doing most of the work as its hotter to the touch ,
can any one ense confirm this ?

btw my pads wear out at the same rate . well the last set did , and calipers were altrasonic cleaned and well bleed

Firstly, are you absolutely certain they were warped - discs very seldom warp - although they are frequently diagnosed as such. Often it's a variation in surface deposition is the problem or, on our bikes, the rotor bobbins gave got gummed up and the discs don't float properly (and require cleaning up to sort them out)

I'll post this article again which explains a lot about these sort of problems and how you should bed in discs and pads.
It's a bit of a long read but well worth it.
