Pulling to left

[garry]

my front brakes pads were changed about 4 months ago and was also pulling to the left seized piston as said before.
the garage supplied and changed the pads and de-seized the offending piston... altogther took them about 20 mins and charged me £60 all-in

If you're not overly familiar with the brake system, which it appears you're not, I'd suggest getting a garage to do the work. It's not worth 'having a go' yourself where the braking system is concerned.
