Are your caliper pistons seized? I found one of the four in one of mine seized :wink: Didnt lock mine on but can do in some cases. Also did you check for clearance between your booster pushrod an master cylinder?

Sounds like your pistons in the caliper a sticking on, May need to check if there seized, also the Master cylinders on he Fawdys can cuase the brakes to stick if its faulty. When you put the discs on did you fit a proportioning valve?

You may need to remove the residual pressure valve at the master cylinder.
