How do adjust the brake pads on hydraulic disc brakes?

I have 2006 Hayes Nine XC disc brakes but I dont know how to adjust the brake pads to fit the caliper into the rotor. Help!How do adjust the brake pads on hydraulic disc brakes?Your Hayes brakes are self adjusting, if someone has pulled the lever whilst there was nothing between the pads then they will have closed together (pumped out), don't use a metal lever as this will damage the pads, hayes recommend in their manual that you wedge thin pieces of card or plastic between the pads to generate enough gap to pull the pads out (the pads will not close up again when you remove the card), then use a screwdriver to push the pistons back into their bores [being careful not to bend the pad mounting post].



Alternatively, if you simply mean that the pads don't align correctly so as to fit the rotor between them, then the caliper's bolt holes are oblong shape, simply loosen the bolts holding the caliper to the mount/adapter, the caliper should move freely side to side, then squeeze the lever (with the brake caliper in place over the rotor) and tighten the bolts whilst still squeezing the lever, this should align the caliper evenly but sometimes it don't! In which case you'll have to lign up the caliper by hand.

All you need to do is put a flat bladed screw driver in between the pads and twist it to push the pads back in to the caliper.



I PRAY that you didn't LOOSEN THE BLEEDER SCREW...



If you did, you'll have to take it to a shop THAT SPECIALISES IN DISC BRAKES and have them bleed the system back out!How do adjust the brake pads on hydraulic disc brakes?you need to loosen a bleeder valve and buy a caliper piston compression tool, it looks like a large bolt through a plate about the size of a pad, with a handle on the bolt. use it to compress the caliper piston back into it's bore, tighten the bleeder valve and install the new pads and caliper onto the disk. you would be well advised to bleed the effected brake after installation. Also, brake fluid is VERY caustic and you need to wash your hands well after use and keep them away from your face. Flush the ground around your vehicle with a 5 gallon bucket of water when done, brake fluid dissolves in water, But is still a major contaminate.How do adjust the brake pads on hydraulic disc brakes?use a c clamp to push the caliper back so they will fit over rotorHow do adjust the brake pads on hydraulic disc brakes?you will need a big C-clamp ..put 1 of the old pads back on and open the C-clamp almost all the way clamp the old pad to the caliper. now before titan the clamp!! u will need to open the bleeder screw let the fluid run into a cup or something. now titan the clamp down till it wont go any more then titan the bleeder screw .. after reinstalling the brakes you may need to bleed the brakes..
