I have a 95 Blazer LS was driving down interstate & truck started shaking and vibrating. 3 days prior my ABS brake light lit up on dash. Tow drivers couldn't get left rear wheel to move to get on flatbed
And said it looks like brake fluid is leaking out of the left break had one mechanic look at it and said I needed a new friend but I don't agree because I just replaced it three years ago he said my truck was towed so I put it up for sale only to have 2 mechanics tell me it was the brakes & maybe a few hundred dollar repair I don't want to get rid of truck so any suggestions on what to do

 

I have read and re-read this and still at a bit of a loss as to what you are saying????

However not uncommon at all for rear brake caliper piston to get stuck. The rear calipers are fairly inexpensive to replace which would solve the locked-up left rear and leaking brake fluid. The ABS light is a different problem, but might just be due to low brake fluid, however I think the Brake light would be on as well.

 

That's what happened to mine, rear caliper stuck. $50 and a youtube video will get you back on the road.

 

I agree with lanny, rear calipers are dirt cheap. $30 plus a core charge maybe? Also learn how to bleed your brakes the correct way/use some wheel bearing grease on the contact areas of the piston to the pads and you will have zero issues with them sticking! I've never once had that issue and I lived in the Ohio salt all my life. Flushing all the old brake fluid isn't a bad idea either while you're at it. Look up chrisfix if you want to see how to bleed brakes easily by yourself.
