My car (1970 Maverick with front drum brakes) is pulling hard to the right when I brake. All new pads and brake lines, wheel cylinders etc. I replaced the front left wheel cylinder because my mechanic friend said it was not working properly thinking that was it, but still pulling hard to the right. The brakes are all four adjusted properly. We discovered last night that my idler arm needs to be replaced. Would the bad idler arm cause it to pull hard to the right? If not what else could it be? I had most of my front end replaced a couple of years ago and it all seems tight except idler arm. Any ideas?
