Re: '90 ZR-1 brake refurbish options

Re: '90 ZR-1 brake refurbish options
Rear calipers installed, e brake adjusted. Apparently it has an automatic adjuster, cycled it several times. You can wiggle the rotors to check engagement and release.

Last time I had the car out, when I got home I noticed my rear "corvette" badge between the tail lights half detached. The old adhesive is fossilized of course, and I'm quickly losing hope on an easy...
