Nissan Brake bias adjuster

[Richard Clough]

By accident I have discovered a Nissan rear brake bias valve with an external adjuster arm.  It sits above the rear diff of the Nissan 4 WD GQ Patrol.  It has a lever arm connected via a big spring to a bracket on the diff housing, so when the body lifts under heavy braking the spring operates the lever reducing pressure to the rear discs to stop lock up under weight transfer.   The proportioning valve unit with its inbuilt lever could be fitted with a threaded shaft to adjust it manually, and bolted onto the transmission tunnel. Connect the brake pipes, bleed, and you have adjustable rears.   It probably costs $300 new from Nissan, but most 4WD Wreckers have them. If your lucky they should be cheap.       --membersozdat------------------------------------------------------- OZDAT Mailing List Please Note:- Send (un)subscribe requests to [EMAIL PROTECTED] Send submissions to [EMAIL PROTECTED] No unauthorised redistribution of this email http://www.datascribe.com.au/ozdatonline/index.htm http://www.datascribe.com.au/ozdatonline/listindex.html http://www.mail-archive.com/membersozdat@datascribe.com.au/ ---------------------------------------------------------------------
