Are there really 5 brake bleeder valves?

    I recently redid the front 3 lines and the master cylinder so I bled the 4 valves at the tires. Recently, I seem to have found a 5th bleeder valve on the "block" that sends brake fluid to the rear.

    Does it also need bleeding?

    Yes. It's the rear anti lock or RABS valve. Bleed RR, LR, RABS, RF, LF
    Do a search, lots of information.

    Well... ****. It's a different size valve for me than the rest but whatever. I guess I need to find tools of the right size and do it it all over.

    When I bleed the RABS should I rebleed anything again?

    Thanks for the answer!

    I would. Also depending on the condition of your bleeders, you may want to consider using flare nut wrenches, it's the right tool for the job.

    Just had to do the same thing on my sister's 89 idi. I believe her Rabs as well as mine and my wife's we're all 8 mm

    Yep, and I didn't have an 8mm flare nut wrench so I used a quarter inch drive six point deep socket.
