Fellow '88 owners know the difficulty of getting calipers for our cars; especially the rear calipers. Old cars and few in numbers does not make for easy pickings. Long and short of things I had my calipers rebuilt at Phoenix Caliper
in Chicago. While I have yet to test them, nor will I for a time yet, they look really nice. Cost was $270 for all four + shipping to and from. Shipping costs will vary depending on who you choose and how far you're shipping. Phoenix return ships via UPS. All told I was in for $350 or $87.50 per. I like that I still have the original calipers to my car. I marked them before hand. Given my frustrating search for calipers I am very happy with this cost. Including shipping I had my calipers back in 8 days. Phoenix says, "Rebuild and return service within an hour of drop off for Chicagoland customers."
I have other repairs on going. I hope to road test my car in a month or so. If you're in need of caliper service you may want to consider contacting Athanasios Athanasiadis @ email@example.com .
