I need to change my rear brake pads on my bike, can someone just confirm the process for me? In the attached picture are the two smaller bolts the pad retainers? I am assuming that the retaining bolts are removed and the pads are slid out. Is that correct? Before the rush of "get a shop manual" comments, this is on a Thunder Mountain Custom and their manuals are hard to come by.
The two smallest bolts hold the pads in. Loosen them and see if you can slide a small screwdriver between the pad and the rotor gently push the piston back in to the caliper. The pads will come out the bottom.
Your brake caliper is a 2 piece design. Referring to your first photo showing the side of the caliper there are a total of 7 threaded items:
-Brake line Banjo Bolt.
-Bleeder screw.
-3 Bridge Bolts.
-2 Pad pins.
The 3 Bridge Bolts hold the 2 halves of the caliper together. Leave these bolts alone. The 2 Pad Pins hold the brake pads in place. You'll need a 1/4 in, 12 point socket or wrench.
Once you completely un-screw the pad pins, pull them half way out. A little bit of force will be necessary. Remove the inner brake pad and note its orientation. Remove the pad pins and the outer brake pad noting its orientation also. Prior to install the new pads, you must push the caliper pistons into the caliper allowing clearance for the new pad thickness.
Once the new pads are installed insure that you pump the brake a few times to seat the pads against the rotor.
I got a floating rotor like yours & was having trouble getting the old pads to clear the brad heads on the rotor & tried taking all the rotor bolts out so the rotor could be moved around & the old pads came out easy then.loose rotor can also be used to spread the pads out before removing them.
