The brakes in my 7office pull the car to the right. The steering wheel included. I changed the hoses but the problem persists. Where should I go, next? New calipers? tony

Mine used to pull to the left until I had the pistons rebuilt which totally cured the problem

Pulling to one side means that the brakes on the offset side don’t work as they should.
Check for sticky pistons, greasy discs/pads and worn or plazed pads.
Also check the alignment of the front suspension.

You overhaul the callipers.
This is not a big task, unless you are unlucky & the pistons are rusty.
Assuming that are in average condition, & not rusted up, they stick on old dry rubber seals, & on a build up of crud on the piston. To overhaul you have to remove the caliper, take the pistons out, take the seals out, & clean every thing. Fit new seals, fit pistons, refit calipers, fit pads, & bleed.

PS. It is a good idea to get the pistons well out of the calipers, while still attached. You can use the brake system to do this. Once off the car it can be difficult to move sticky pistons.
Remove the pads, & apply the brakes with something about 3/8" thick in place of them, to stop the pistons coming right out. Then remove the calipers, & piston removal should be easy.

You can remove pistons with compressed air, quite easy but you have to be careful they suddenly release like a bullet so you need some rags and a piece of wood in there to absorb the impact. One piston will likely release first the second a little tricky as the now unblocked brake fluid hole has to be plugged enough so air pressure can push out the other one.
