Brakes - What's minimum thickness allowed?

http://www.fmcsa.dot.gov/rules-regulations/administration/fmcsr/fmcsrruletext.aspx?reg=393.47

 

1/4"...............................................

 

Read the regs, 1/4 inch does not always apply.

 

True, but 1/4'' is the general rule in a DOT inspection.

 

True.

Steer axles with continuous strip linings can go down to 3/16".

So it is 1/4", (3/16" steer), or "worn to the wear indicator if the lining is so marked." The wear indicators are often more than 1/4", but the indicator is the limit.

 

1/4 equals 4 /16

minimum thickness for tires and brakes is 2/32 but tires have other various reasons they can also be put out of service

 

i stand correctred., they post 3/16 which is slightly less the 1/4.

that's a LOT OF LIFE left to be throwing away.

 

Not really.
