hi, ive just bought a black 1999 (T reg) manual glanza a couple of weeks ago only 60,000KM's on it. The car had been sat around for a few months and didn't have an mot when i bought it but had a good look over it and it looked clean enough. I had to replace the manifold gaskets, the battery and get part of the exhaust welded up then put it in for a MOT but it failed on: Headlamp aim too high (should be an easy fix) 1.8 offside rear mechanical brake component has restricted free movement 3.5.1j offside rear brake binding 3.7.A.5a parking brake efficiency below requirements 3.7.A.10 Front brakes imbalanced 3.7.A.2d so i took the brakes apart and all the brake pads are nearly new and the discs are in good condition but the rear drivers sized caliper has seized. Does anyone know where i could get a reasonably cheap rear caliper (second hand probably)? and any ideas on why the front brakes are imbalanced if the pads and discs are in good condition? any help is much appreciated cheers
