Where do I begin? Took my older 98 Chevrolet suburban in because antilock warning light was illuminated. Technician was positive that it needed a new antilock brake control module after they replaced it still didn’t work. Turns out. It was the speed sensor So after replacing it, everything The antilock light went off, but after getting it back, the brakes Started lock out for no apparent reason? This was a totally new issue that only arose after taking it to them and getting it back. So took it back to them and they replaced the other speed sensor, but the issue is still present. I am done with them, hard to find a knowledgeable mechanic who understands older vehicles On top of that, I wanted them to change a shock out for me that I had already purchased technician tells me that it is the wrong shock when it is clearly not, just shaking my head. Now I don’t know what I am Going to do about my brakes as they are still randomly locking out on me
