MG MGA - Brake caliper not releasing

One front brake caliper on my 1600 is not releasing.
What should I be looking for?
Thanks.

Rubber brake hose to the caliper. When did you change them last? Good as place as any to start with, and pretty common as well...........gets old, and acts as a bit of a one way valve....

Hose, good suggestion. A test is to open the bleeder. If fluid comes out, and brakes release, the hose is the culprit. A's have an odd set-up tho, with a centering pin in the piston. If that assembly gets corroded, there's no easy fix except a rebuild. Suggest that you remove that pin and use MGB caliper pistons to alleviate the issue...if it is one. Good luck. Peter C

I worked a lot on 2-stroke and V-4 Saabs. Sticking calipers were very often corrected by replacing brake hoses. The rubber inside swells with age decreasing the inside diameter and prohibiting the brake fluid from returning.

I have read several articles (this site) re: converting 1500 drums to 1600 disk brakes. I now have 1600 hubs (wire wheels) and rotors, but no calibers. Are they available? I know I can use the adapters and use MGB calipers. Will the very early MGB "A" frame with wheel assembly bold under MGA woithout modifications, or must you still mill for the shock absorber? Do you use the MGA or the MGB shock. Do you need to change the MGA master cylinder? What is my best option? thanks-
