I've got a customer that has a 99 GMC K3500, 5.7, auto, with the hydro boost brake booster. His brakes are extremely touchy and lockup with very little pedal pressure. Brakes are almost new on all 4 corners. Before I replace the hydro boost unit just want to see if anything else could cause this problem. Power steering works fine, if anything it is also a bit sensitive.

All 4 brakes lock up, they are very touchy and lock up with little pedal pressure. If you're not careful it will put you through the windshield!

 

Rears are drums and brakes front and rear are in very good condition. I did flush the power steering fluid as it was very old.

I just had this truck back in the shop for a different issue. Previously I had flushed the power steering fluid and after a quick test drive yesterday found the brakes to be working correctly, no more instant lockup so the flush did the trick.

I've seen similar issues regarding the hydroboost. Contaminated pwr steering fluid or sticky valve in the hydroboost. If a flush fixed it, you probably got lucky. Watch for the problem to sneak up on ya again when the summer time heat starts to come around. If so, then you'll need to look at the hydroboost again.

      Want to End Your Technician Shortage? Focus on Retention!
      By Joe Marconi in Joe's Blog
         5 comments
      I recently spoke with a friend of mine who owns a large general repair shop in the Midwest. His father founded the business in 1975. He was telling me that although he’s busy, he’s also very frustrated. When I probed him more about his frustrations, he said that it’s hard to find qualified technicians. My friend employs four technicians and is looking to hire two more. I then asked him, “How long does a technician last working for you.” He looked puzzled and replied, “I never really thought about that, but I can tell that except for one tech, most technicians don’t last working for me longer than a few years.”
      Judging from personal experience as a shop owner and from what I know about the auto repair industry, I can tell you that other than a few exceptions, the turnover rate for technicians in our industry is too high. This makes me think, do we have a technician shortage or a retention problem? Have we done the best we can over the decades to provide great pay plans, benefits packages, great work environments, and the right culture to ensure that the techs we have stay with us?
      Finding and hiring qualified automotive technicians is not a new phenomenon. This problem has been around for as long as I can remember. While we do need to attract people to our industry and provide the necessary training and mentorship, we also need to focus on retention. Having a revolving door and needing to hire techs every few years or so costs your company money. Big money! And that revolving door may be a sign of an even bigger issue: poor leadership, and poor employee management skills.
      Here’s one more thing to consider, for the most part, technicians don’t leave one job to start a new career, they leave one shop as a technician to become a technician at another shop. The reasons why they leave can be debated, but there is one fact that we cannot deny, people don’t quit the company they work for, they usually leave because of the boss or manager they work for.
      Put yourselves in the shoes of your employees. Do you have a workplace that communicates, “We appreciate you and want you to stay!”
