Caliper clearance - The 1947 - Present Chevrolet & GMC Truck Message Board Network

63longfleet · 11-04-2018, 08:07 PM

Well i finally got around to buttoning up my disc brake upgrade and need some info from the big brains in here. I am running Center line 15" rims and the calipers arent rubbing but there is less than a 16th of clearance. Is this going to be a problem down the road as they get hot. Prolly a stupid question but i have learned not to take anything for granted on this project anymore. Thanks in advance.

That shouldn't be an issue.

Thanks Cap, puts my mind at ease.

Nah, should be fine. Mine have only a little clearance on my front M/T wheels, but never had an issue with them.

Also, first place to look when you get a funny noise; its not unusual to get a twig or little gravel piece in there to make a funky noise for a few minutes lol. Ask me how i know.

Just make sure you don't get the weights for balancing clipped onto the inside. I had the Cpp modular drop spindles and they cleared the wheels but no the weighs.

Running original Centerlines on my '63: no problems !

After a little more checking i found that the calipers themselves were at least a 1/8th away from the rim, but the caliper mounting on the spindles were rubbing just a little. So a few min. cleaning up the casting slag from the edges and all is well once more. Thanks for all of the responses. I dont think i would be as far along as i am with this build if not for the help and guidance i have recieved from this group

I put disc brakes on a 71 Nova years ago and had a little interference between the caliper and wheel. I took a grinder to the caliper and removed a very small amount, and all was fine. I drove it several years that way.

One word of caution, I did find that the caliper and/or caliper bracket flexed a tiny bit when brakes were applied, so even with clearance OK under static conditions, it rubbed a tad when braking. I took the grinder and took off a tiny bit more material, and all was good.

Did the same thing on 65 Nova.
