When I come to replace my Pads in the Hope M4 brakes which I have now got, do I push the pistons in to accommodate the extra thickness of the new pads or do I as well have to re bleed or top up the brake fluid to prevent the pistons from travelling too far out causing sticking on the rotors? Am I making a mountain out of a mole hill? I have watched the hope movies on bleeding and setting the pistons, but there is nothing on replacing pads!
Place educate me Guys!
Before you install the new pads, get some brake fluid and a couple of cotton buds and give the pistons a bit of a clean. Then it should be a simple case of pushing the pistons back and slotting everything back together. Then feel warm inside for having done it yourself.
(This assumes that Hopes are the same as Shimano and Formula calipers).
shouldn't need to re-bleed or top up.
Just push all pistons back in using old pads and a suitable lever, stick new pads in, reset pistons, job done.
I have found with my M4's that the piston setting part of it is pretty important and worth spending a bit of time getting it right.
Cheers!
