Brakes: wrong size?
Hey everyone,
I can't seem to be able to put my calipers over my rotors. I have a 79 ranchero, and i bought new rotors and new brake pads. The calipers are stock. I compressed the piston in far enough to where the brake pad was sitting behind the wall, and with the brake pads in, it will still not fit. Either the rotors are too wide, or the brake pads are too thick. The thing is, there was only one option for the brand of rotors (wearever) and one option for the brand of brakepads (bendix). Then i measured the rotors to be 10 3/4, which should be stock. The brake pads look pretty thick, but they fit perfectly. They could possibly be for the bigger rotor and caliper, you think? Either way, the rotor is too wide for the caliper to fit over w/ the pads in. What does the problem sound like to you guys? And also, when i left the inner pad out, the rotor would still not fit between the pad and the inner wall of the caliper, so if the pads were outside the wall (like they should be) it could not possibly fit. Thanks!

It sounds to me like the calipers are still not depressing in enough. They could have a ridge of debris built up from the years that they did not go al the way back. The debris would build a ridge.
Remove the calipers and have a brake shop look them over to see if they depress all the way in . If not I say buy some new ones. They are inexpensive to buy.
The other thing could be that maybe the place you got the pads from gave you the wrong ones. they maybe are for a truck or larger vehicle. You can recheck there.
The rotor sounds about right.
I have heard where some guys have taken and ground down the pads to make them fit, but that causes uneven wear and premature wear of parts.
I start with having the Calipers checked if they need replacing.

Interesting ordeal with the pads and rotors..... You might want to evaluate the distance that the puck retracts flush to the caliper support bracket. Leave the brake pad that is farthest away from the puck on and remove the pad nearest the puck ---look to see if the puck retracts fully...if in doubt break open the bleeder valve a little and gently wedge the puck back also make sure the disc is bolted on the hub securly..now if the puck retracts flush with the caliper support bracket and you still cant get the nearest pad in ... you got the wrong pads...or wrong rotor.. and if the puck does not retract flush with the support bracket you got a caliper problem..its sticking out to far and won't let pad in place.. leonard

thanks for your help. i ended up getting them on by force, but after i bolted the caliper on, i had to turn the rotors to get them grinded down a little, so now they move fine. it was barely too much.
