My brakes are pulling to the right . The two fronts are on one circuit the rear (live axle) are on the other .

I've re- bled the left front but it hasn't improved are there any other factors I should consider ?

I'll put my money on a sticky or seized caliper (probably front), particularly if they are cast iron ones.

If so, they need to be taken off and inspected for signs of damaged seals and/or corrosion between the pistons and caliper. Then either new ones or a rebuild depending on how bad it is!

Worth noting that it'll generally pull to the side that is working more effectively.

It'l be a sticking caliper - I had the same , and left too long (when I did get round to sorting it , I had 1 pad 1mm thick while the other was 10mm )
I had to strip , clean , and replace the piston seals to cure it - then the other side did the same

thirded - sticking piston. I had one that cuased a bit of drag - passed SVA ike that - bdidn't pull.

Had to replace seals, piston and give it a good cleaning.

Did the other side as then that was dragging more than the good side, not much but more.

Thanks . sounds fairly conclusive I did re furb my calipers with new seals etc but that was many years ago . sitting around in the mean time has probably allowed a bit of corrosion in . I'll have to whip one off (left ) and check or just keep an eye out for some new ones on Ebay or in the classifieds here ..Cheers
