Rear Caliper Replacement
 

I've got to do rear brakes soon on my truck. There is no real rush, but I do need to order rear calipers as the left rear is locked up and I will be replacing both. I know to replace calipers and I know that the brake hydraulic hoses are still good; my question is that if need to get ACDelco calipers (from online) or if I can get aftermarket brand calipers from the auto parts store and still get good results.


The parts cost and core charge are about the same, but if I order online I have to pay to ship it back to get the core charge refunded and the shipping cost is non refundable.

A locked up caliper will generate heat, the hose might look good from the out side, but failed on the inside. hose is cheep.

you should be able to source locally with good results

Make sure the brackets and hardware come with the rebuilt calipers. Let us know BEFORE you bleed them, there's a trick that will save you a TON of grief.

Thankfully the caliper isn't locked the applied position, it's the opposite and is starting to rust real bad and it is never been able to get hot unlike the other 3 if I do a lot of stop-and-go traffic. As the bleeding procedure is it anything special? At the shop we typically pinch off the line using a special brake hose clamp before removing the caliper, then install the new caliper and remove brake hose clamp, let them gravity bleed for a minute or so, and do a power brake flush using the flush machine.

Definitely needs the brackets! Gravity bleed both first, DON'T pump the pedal. After the gravity bleed, slowly pump & release to bring the pistons out. After the pedal is firm, then hold pressure, don't pump, & bleed like normal. Usually only takes one or two times like that and it's done. Rather than flush the ABS, just let it gravity bleed until the fluid comes out clear. If the EBCM injests any air at all, you'll need to do the automated bleed with a capable scanner.
