Rear brake caliper bolts.....Is bottom bolt supposed to move like the top? (1 Viewer)

[BullElk]

I have just noticed the bottom bolt will not budge as if spring loaded like the top bolt. Is that proper operation?

Thanks.

One of those bolts have a rubber ring around it. If the top bolt is without the rubber ring, then the bottom bolt has it and it is getting swisted as you try to turn it. Both bolts should come out.

The bottom caliper bolt (sliding pin) has a rubber dampener sleeve on it to help keep the caliper from rattling and vibrating between braking operations. It is normal for the caliper to be hard to move by hand.

What I noticed was the top bolt moved easily but the bottom bolt on both sides would turn with a wrench but not slide in at all. I finally got the caliper on, drove it a bit, took off caliper and the bolt was in further looking more normal.

Rear caliper have "slide pins" attached by a 12mm bolt. The pins slide into torque plate. Each pin has a boot. These boots should be replace with ever pad replacement. Otherwise, they may fail to seal out water. Water entry will result in corrosion and freezing slide pins in torque plate. Corrosion also eats the pins port, damaging a costly torque plate.

Toyota recommends slide pins be grease.
