Does anyone know the brake line diagram for an 99 toyota avalo ?

Asked by Aug 16, 2016 at 10:44 AM about the 1999 Toyota Avalon

Question type: Maintenance & Repair

All of my brakea went out the other day. I know
there was a leak in the rear brake line so was going
to cap off the rear brakes at the master cylinder
but still have no brakes even after bleeding the
fronts. Was thinking maybe i capped the front line
instead so i really need to see a diagram from
master cylinder to brake lines front and back.
Thank you

You cannot cap off brakes lines on a vehicle equipped with anti- lock brakes, this causes the unit to sense that what ever you capped off excess pressure in the ABS unit and feeds back into the master cylinder ruining it and can also damage the valving in the ABS unit itself. Put it back to stock, try bleeding the brakes properly and hopefully you wont windup replacing a very expensive ABS and brake master cylinder.
