Brake Caliper Rattle???
I replaced my brake pads, lines, retainer pin, and wheel hubs in the last two weeks. I though I was getting a bad rattle in the front end from bad bearings but with new hub I still have this rattle. Just went for a ride and confirmed the rattle.
Is it correect that with no preasure one the system that the calipers can be shaken by hand :confused: I just reach down past the wheel and can move the caliper about an 1/8" or so back and forth????
This doesn't seem right to me but I went to the trouble of replacing the retainer pins this time as well. This rattle is very noticable, and getting on my nerves :mad , also think something is just flat wrong.
Anybody had something similar? Anyideas what to check?

Check to see if you have the pad tension spring. There is a spring that pushes from the caliper to the pad. If this is left out then you get a rattle noise that goes away when you push on the brake pedal.

The OEM break pads had anit-rattle pads between them and the metal surfaces.
Instead of using these anti-rattle pads, I put some black RTV on the back of each new break pad; nearly a year later I've had no rattles.
Also double check that none of the break pad clips have broken.

If I read your post right, you can move the caliper by hand? You should NOT be able to move the caliper at all. ( and the pads if installed correctly should be snug in the calipers too). If you can infact move the caliper 1/8" by hand, something is wrong in its mounting to the bracket.

Re: Brake Caliper Rattle??? (ittlfly)
The caliper definitely moves. It moves within the bracket, the bracket is locked down to the knuckle solidly. I the "repair kit" I order from NAPA with the retainer pin there were also to curved pieces, I don't know if this a spring like piece that has been mentioned.
Just so I make sure, on a '89 nothing but the retainer pin hold the caliper in the bracket. Maybe these other piece help to keep constant preasure, but I don't know how they fit into the picture? These clips look like a "S" shape and are about 1/2 to 3/4 inch in size.
Any ideas
:confused:

Re: Brake Caliper Rattle??? (Dolfan)
OK, I think I have it now :rolleyes: On the front calipers the outside pad presses into the caliper with the circle of prongs that hold it tight into the caliper, so that pad wouldn't rattle. These other clips must fit on the piston side pad to hold them tight, I guess maybe they fit into the hole of the piston and hold the pad :confused: need to check it out tomorrow.
This should help to make sure the pads are secure, but I still am unsure how this will secure the whole caliper????

Re: Brake Caliper Rattle??? (Dolfan)
Those clips fit on the ends of the pads to prevent rattle (as I remember). However they will not affect the any loosness if the caliper itself. If the mounting bracket is torqued onto the knuckle, have you checked to be sure it isn't broken and solid? If it is OK then the problem is in the caliper itself. Are these OEM 12" or after market? Are you using the correct size pin (thickness) to connect the caliper and mounting bracket? Just a few thoughts.

Re: Brake Caliper Rattle??? (ittlfly)
ittlfly and others thanks for the help. The clips helped quite a bit. Once they are on the pad they work to maintain constant preasure between the pad and pressing against the caliper bracket. This takes up the slack that I was finding without and allowed the caliper to rock back and forth a bit.
Did a test drive about an hours ago, and it is very smooth and quite. Just in time for today's autox. I guess I'll have to find something else to blame a bad time on now :D :lol:
