New stock disc brake calipers

Hi everyone,

I'm converting my car to rear stock factory discs over the drum brakes. I have to go stock disc because I have 14" rims so I can't put on anything bigger, and I know stock calipers do fit inside a 14" rim. Buying bigger wheels is an expensive option so not going to happen.

I know that 82-86 (or thereabouts) calipers had a kit you could buy which fixed a problem where the e-brake didn't work very well. My question is, if I go and buy remanufactured calipers will they have the fix applied to them or will I still have to get hold of the overhaul kit from somewhere?

Thanks,

I am not sure about the ebrake kit but my remanufactured calipers from advance auto have never given me an ebrake issue it holds tight all year every year. Also I think the drum axles had a different hub diameter that does not fit in the factory rotors.

Thanks for that, makes me feel more confident in getting re-manufactured calipers now. These are going onto a diff that already has disc axles so I should be good there.

These are the same as what I run. Still no idea if they have the kit but my ebrake works

Re: New stock disc brake calipers

Your store bought calipers are unlikely to have the recall kit installed. May or may not still be available:

Part Number: 18019028 from GM Parts Direct, listed as "Actuator" and included parts for both rear calipers, pistons, springs, seals, etc.

Thanks for the part number. To avoid returns on the product, wouldn't they want to have the recall kit already applied to re-manufactured calipers?
