I guess I'll be finding out, it's on the to-do list. My truck has 4 wheel disk brakes so maybe I won't need one.

 

Did you get your brakes bled?

 

Sorry it took so long to get back to you. I ended up having heart surgery (triple bypass), then my wife of 48 years died so the blazer never got looked at until recently. I got the meter and while it seem cheap and next to no instructions, it worked. I have transportation now and appreciate the quick replies in this forum.
