1972 Blazer rear shakes when braking

[jmillsUT28]

Working out a few more bugs in the blazer that I just bought. One is when I start to brake there's a rattle/vibration shaking in the rear. The shocks do look out so that might be a problem. What else could be the problem? Anyway to test it to see what is worn out?

Your sway bar bushing could be worn out.The one in my burb was worn and the rear was wobbly.

I would pull the drums and look for things such as broken shoe retainng pins, broken shoe pivot stud, damaged shoes, broken/missing springs, etc. Any of these will result in loose parts and/or erratic braking. Also check that the brake shoes have been installed in the proper location. Each pair of shoes has one with a long lining and one with a shorter lining. I can't recall which one is supposed to go in the front or rear position, but it makes a difference. Do it wrong and the brakes will be "grabby".

Vibration when braking is usually in the brakes. Make sure your wheels are tight, if they are and u feel the vibration in the rear I would start with doing brakes in the rear.

Drums are warped.

[Mr Banshee]

Agree with Classicstyle, when braking if shaking occurs or a pulsating pedal is usually the cause of warped or to much run out in the rotors and drums.

Shocks can and will contribute to this as can loose u-bolts. But drums are most likey suspect.
