thud and turning while braking

Recommended Posts

whenever i have to firmly and quickly use my brakes, i hear a loud thud sound and my  truck pulls hard to the left. my mechanic cant find the issue. could this just be a bad brake chamber?

I have several seized anchor pins on my trucks, never get this. When I drive other people's trucks I do sometimes.  Adjusting the "self" adjusting slack adjusters takes it away for me...

As swishy said, "self" adjuster gets so far out that S cam goes over center, effectively releasing that brake, giving you unsynchronized brakes. This is why i always liked manual adjusters, you gotta get out and set them, and the truck will stop straight every time. Added bonus is while youre in there you gotta look at things like brake linings, air hoses, springs, youll hear if a maxi is leaking, etc. Downside is if you hire incompetent people that won't check them then they'll rear end someone at some point.
