Rear Caliper Has Play Options

[trdproven]

Might need the forum guys help on this if you've already experienced it. Can't seem to find the right results from the search function.

I have play in the rear calipers. My guess is thats either normal or abnormal. So if its abnormal I'm guessing this is the pins causing the pad to move, and i get some clunks.

1. Do I just regrease the slider pins? I noticed the top is not a bolt, didn't really look at it but if anyone has some insight how this is removed that would make me anticipate better but either way I can take a look at it.

2. Do I just get new calipers? which would solve the problem anyway.

3. Get new brake pads.

4. Buy new Pins and just replace it?

I'm sorry, I'm still not clear. Are your rear brakes the standard drum-in-disc setup for a Celica, with a shoe-based parking brake incorporated into the caliper-based driving brakes, or are you using a system which only has calipers? Again, if you have a system where the parking brake is incorporated into the caliper I'd love to get the details.

That picture is of my rear brakes. If you pull the rotor off, you'll find a small drum brake setup with all the usual hardware. Smaller, yes, but still all the same components sans a hydraulic wheel cylinder.

As for regreasing the sliders, you're correct that the caliper is only held to the caliper bracket with one bolt. To get the caliper off the bracket, you simply remove the one visible bolt, then slide the caliper off the bracket. However, this can only be done after the caliper and bracket have been removed from the rotor.

The caliper doesn't actually slid on pins; rather, it slides on metal bushings. One bushing is held to the caliper by a rubber dust boot -- this is the bolt you remove when releasing the caliper from the bracket. The other bushing is bolted to the caliper bracket, aka torque plate -- the bolt head is hiding under that plain cap. The pin boot -- yes Toyota identifies a pin boot but no pins -- seals the point where the caliper slides onto the bushing which is bolted to the bracket. Properly you should use soap base glycol grease to lubricate the brakes; at a minimum use a non-petroleum lubricant to avoid damaging the rubber components.
