Sport rear brakes on a NA miata

[zukitek]

I recently got.tired of my life being threatened by the brakes on this 97 miata I drive everyday and I installed rear rotors,calipers, and brackets from a 2001 NB with sport brakes . Now it has fantastic brakes on the road. The only issue I have now is that my parking brake wont stay adjusted . 4 times now ive adjusted it at the allen adjusters and it works ok for about 3 days and then it gets to where it wont hold on a hill. Anyone else had this?

Try tightening at the parking brake. I assume you are talking about adjustment at the rotors. Where ya been?

Yes that is what i was talking about. The adjustment on the caliper that you take the 14 mm plug out to get to. Walley i have been around. I have been doing alot of track days with chin motorsports so that has kept me from tt a bit. Im still developing the 240. Uncortunately this year ....scca tt dates fell in wierd spots for me schedule wise. I really think I have a bum caliper causing this issue. I have 2.more remanufactured calipers on the way to see if this corrects my parking brake problem.
