just purchased an 71 510. I drove the car , seemed fine. It has been lowered has fron strut camber plates. The camber out back seems to be a neg 1.5 apprx.. Also has a rear swaybar.After purchasung the car I took it out for a good test moto. After about 20 min of pushing the car a little, something got hot or stuck or was sticking in the braking system. The brake pedal got pumped up and something felt like it was dragging. Dont know what, I jacked up the car and found some resistance when I manually tried to rotate the rim, both sides. Same when I removed the rims and manually tried to rotate the IRS. Thanx in advance for the help. Tim:ylsuper

First of all, air in the brake lines will expand when things get hot.

If you have purchased a 30 year old car, I would 1st check all of the brakes and bleed the lines. Not knowing the overall condition of your car, it's pretty hard to tell.

Bleed the lines for sure. and check that the front calipers arn;t siezed... I have run into that a few times. Cars been sitting for years brakes dont; wanna work right anymore.

For sure bleed the lines. and check that the calipers arn;t all incusted in rust. I have run into that a few times.

interesting... why did it do that. said page can't be displayed so I tried agian and they both worked?

check that the front calipers arn;t siezed... I have run into that a few times. Youwere right thanx
