i recently just did my front brakes on my car. i replaced the calipers, hoses, pads, and rotors, and my car still pulls to the right while braking, i looked at my rear brakes and the driver said wheel cylinder is leaking fluid. will that cause my car to pull?

 

If the caliper is leaking, it very well cold be seized or low on pressure causing it not to fuction as well. if this happens, the other side of the car will slow down faster causing it to pull that side.

Its just like running straight and then grabbing onto a pole with only one arm. It will yank you to that side. ( I know this is a dramatic example but it gets the point across ).

 

the front are fine, it is the rear wheel cylinder that has a leak.

 

yes, because you are braking in the right rear and not the left rear. and thus a pull
