'72 Ranchero GT Brakes Locking Up
Hi. I'm pretty new to classic cars, so I hope someone here can help me out.
I just recently got a '72 Ranchero GT, 351C Engine. It needs work, but it works well, for the most part.
When the brakes are hit in a normal fashion (pressing them down gradually), they work great. However, when the brakes are pumped twice, the rear brakes lock up and the tires spin. I know old cars' brakes didn't have ABS in them, but I thought that the brakes used to lock up when stopping too quickly, making it where you were supposed to pump the brake. The right-rear tire seems to lock up sooner than the left does.
I had the brakes checked and the mechanic said that the brakes looked practically new, that I didn't need new ones, so I don't know what to do now.
Could someone help me out here? Thanks in advance.
