Tim, I’d not be too happy at the pulling to either side if it were me.As well as what Mel writes, do the linings look as though the contact areas between shoes and drums look the same on both sides of the car?I really can’t remember touching the front brakes on the car at all when I had it here, although I did fit reconned Phase 1 rear cylinders, which took forever to stop weeping.I wanted to chuck them down the road and fit the Phase 2 rear cylinders, but TE was happy with them as they were.It didn’t get much use in his ownership.Perhaps 100 miles max.As the fronts are not seized(?) on the right hand side (they DO seize, solid or partially, very easily!!) I’d be whipping all 4 of the pistons out for a clean up generally, and a regrease with the red stuff.This is almost an annual event for me on Phase 2 fronts.They really work very well indeed if all 4 are functioning as they should, especially so on a lightweight car such as yours.
As a matter of interest, it is quite possible to believe that your Phase 1 rear brakes are perfectly OK, especially if the handbrake is functioning well, when in fact, hydraulicly, they are seized solid (and may have been so for years) especially if you are not a regular MOT man.It is quite legal to request your tester on the now voluntary MOT test, to use a Tapley meter, instead of checking the car on the MOT brake rollers.The Tapley meter will show all is well with the overall hydraulic braking performance, since rear brakes offer much less assistance, working or otherwise, and the hand brake will easily lock the brakes on the mechanical circuit, leading to the false conclusion that the rears are OK.
