I have a 99 GMC Sierra (new body)w/25K miles, when I am braking at
slower speeds(under 5mph), the ABS comes on, the ABS light does not
come on. I took it to the dealer and they told me I needed four new
rotors. For a $1000.00 they said they would try this to see if it
works. So I decied to do this myself. I pulled the front rotors, they
were indeed rusty, Pep Boys wouldn't touch them so I ordered new ones
and will put them on this weekend. I will try the front rotors first,
see if this fixes it.
When I looked at my reciept from the dealer, I noticed that the tech
who read the codes said the L/F sensor was open...The dealer did not
mection this as a fix.
After reading several post, for older body trucks, it mentioned that
cleaning the ABS sensor area would fix this problem 95% of the time.
Is this true for new body trucks as well? I noticed the sensor seems
to be mounted in a hole that is drilled into the bearing housing,
seems easy enough to clean.
