Ok the 4 runner isn't here yet. I have a friend who had her brakes done, and now under hard braking all wheels will lock up and not release. I have been told that the system is bled and everything else is normal. The brakes were not done at a shop so she can't take it back. Its gonna be dropped off here, so any info would be appreciated.
Does the ABS system require bleeding and could that be the problem ?
Is there an ABS sensor at the wheel, and could that be the problem ?
I am going to look at the MC, and see if its jamming and not releasing.
