Brake pad question

Post by Gunnar Már » Sun Jan 06, 2013 12:00 pm



I'm in the middle of a all brake overhauling, including all rubbers new and all brake pads new.
To my surprise when I looked at the old rear pads they where thicker than my new ones by 1,5 mm.
Are the rear pads suppose to be thicker than the front ones?
Maybe it's just different manufacter but I,m a bit surprised.

Seems to me that the front`s would be thicker because of the weight transfer during stopping. That said, maybe the new rears were mislabeled.

for the aspencade that has the vented front rotors , the brake pads are thinner than the pads that fit the standard solid rotor. They look the same and will fit either caliper but you cant fit the thick pads to the vented rotors. 8-)

So I´m fine installing my brand new pads even tough they are a bit thinner.
That is great I was a bit scared I had to order new ones and that would delay everything else I´m going to do to my bike this winter.

Thanks for the info

A lot of brake pads will fit the front or rear caliper of another bike, so many manufacturers make a pad that is intended for use on the front brake, but that you can use on the rear where it fits. The front pads are generally thinner than the rear pads, because it allows better heat transfer through the brake pad material to the piston and caliper.. Heat is the enemy of all brake systems, so we try to have the disk dissipate heat, but also the backing plate on the brake pad and the piston/caliper help in the dissipation of heat if we can get the heat to transfer through the pad material. Sintered pads are quite good at conducting heat, so they are sometimes thicker than standard pads (due to the better heat transfer), but either way, everyone tends to go for a thinner pad material to promote transfer of heat from the disk/pad interface to the caliper to allow for more consistent and better braking.

No harm using a thinner pad on the rear.
