Default Brakes Dragging on 1993 ZR-1

After noticing that my front brakes were dragging slightly I had the pads replaced. This made the mater worse.

What other things should I replace to solve this problem.

Should I replace the calipers or have someone rebuild them?
Should I replace the brake lines?

Thanks,

Dave Noble

Try lubricating the caliper slide pins. I use high-temp grease.

Thank you for your reply, I did have that done when the pads were replaced. I am wondering if the Calipers need to be rebuilt or if the hoses could be breaking down internally. The problem seems to get worse as the car is driven and the rotors heat up.

I would check and maybe replace your brake lines. They can look good from the outside, but be bad on the inside causing the fluid not to flow properly or not even flow at all. A way to check your hoses is to disconnect them and blow air through them. That will give you a good indication of the condition of them from the inside. If any are suspect, now would be a good time to replace all 4 hoses. JMO Good luck....

Thanks for your reply, I think I will replace the Calipers or have them re built and do the Brake lines at the same time,

While you are replacing stuff, make sure that you purge out all the old brake fluid & replace it. You want to remove as much crud as you can.
Sounds to me like a sticking caliper, seen it before. But, it should have been obvious when the calipers were being retracted for the install of the new pads...
That part doesn't make sense.

I appreciate your reply and will probably do the Brake lines as well as the calipers. Hope I can keep the original calipers by rebuilding them

Get braided stainless steel brake lines, it firms up the feel of the brakes. Unless there was water in the brake lines, the calipers should be rebuildable. Given the age of the car you may want to do the Master cylinder at the same time. More often than not the MC goes out a few months after doing the rest.
