Found out that one of the pistons on my RR caliper was frozen when I was trying to replace the brake pads and discs.

Now, can I replace just the bad caliper or do I have to replace both sides. The replacement parts I bought and the ones on the car are both ATE's.

Thanks.

The general consensus is that both sides should be replaced, because the rebuilt caliper will probably grip a bit better with a given amount of hydraulic pressure.

But, others have replaced one caliper and have been successful.

Your odds of success are greater for the rear calipers because they provide less braking power for the vehicle.

If you replace one, and the vehicle pulls to the side that was replaced........you'll know........

Thanks Brian,

I'll replace both sides. Have the parts. Might as well do it.

I agree.........if finances are not an issue, then it's worth the peace of mind.

Some folks are in difficult financial situations and a one caliper replacement might be successful for them.

I replaced one caliper on the front of my POS Dodge B-250 van. It started to stick and smoke the pads. Certainly wasn't going to do the extra work to pull the other caliper on that vehicle.

It works fine........no pull.
