hey guys i have a altis and that blasted car only giving me brakes prblem (brakes binding) serviced and changed practically everything and now whenever i mash the brakes the sterring turning to the left, what could cause that now?

could be one of the front wheel that locking up causing it to pull on one side.

WRT brakes binding sometimes the disc pads you does buy in the parts place does be thicker than the oem ones so when you install them they may bind. had this problem on a b13 and problem was solved by adjusting the rod on the brake booster.

Brake binding is caused by sticking pistons in the calipers. Too, a bad rubber hose to a caliper collapses on the inside locking in the pressurized brake fluid, causing the pad to apply pressure on the rotor constantly.
With reference to what the previous tuner wrote, conversely if the rod in the booster was interfered with, and was extended too long, then a constant pressure will be applied on the master cylinder piston, engaging brake system. The front brake will respond first, hence binding can occur, most likely in both wheels.
The car would not free-roll, pads wear prematurely, heat is generated, grease melts from the wheel bearing, which would ultimately fail.

If your steering turns to the left when the brakes are applied, it means that the left front wheel is braking more strongly than the right front wheel.

If the rotor on the left is damaged the brake will hold more.
If the piston in the right caliper is seized it will hold less.
If you have different brands of brake pads on the front wheels, they could cause that problem also.

Both wheels are supposed to be equal in braking force. That problem you have could be pretty dangerous, especially on wet roads.

Yep,you are "driving around" the front wheel which is binding.You may even find whilst driving normally in a straight line without brakes applied vehicle is tending to drift to side where calipher is not functioning properly.
The solution is most frequently solved by servicing brake caliphers which requires a calipher service kit and possibly sliding pin(s).
