Front brakes locked and rear drag
Hey, I got a 91 RS Camaro, I just installed D52 Wilwood calipers on the rear and replaced the front two with OEM calipers. Now I'm running into the issue of my front calipers being completely locked after bleeding and the rear calipers are dragging. I replaced the master cylinder and that didn't help. Any advice is much appreciated, thank you.

Sounds like a proportioning valve issue

Are the brake hoses original? If so, they may need replaced.
Did the prop valve valve shift offcenter when bleeding?

Re: Front brakes locked and rear drag
When the fronts are locked crack the bleeder and see if they release. If it releases pump the brakes again and get them to lock, now crack the line at the MC and see if they release. This will isolate where the pressure is being held.
