efp0wa Posted July 31, 2011 Share Posted July 31, 2011 Hey, Need to bleed L300 brakes. The Manual mentions to bleed the right rear brake, the front brakes then the 2 nipples on the G Sensing Proportioning Valve (G.S.P.V.), it mentions there is 2 bleed nipples on the GSPV valve and to blee highest to lowest on the valve. While in fact there is only 1 nipple on my GSPV valve. So should I still continue with the way it instructs to bleed. Rear Right-Front Left, Front Right-GSPV valve? I know it's a weird question, I know on a car to start with brake furthest away then to closest to master cylinder but i've never dealt with one of these GSPV valves before.

2JZKP Posted August 2, 2011 Share Posted August 2, 2011 yes id bleed it like it says to man, youl only need to bleed right rear as the fluid for the rear brakes travels through the left rear then goes onto the right rear so there will be another solid pipe coning out of lr cylinder bleed hole and going to rr cylinder sometimes you dont need to bleed the proportioning valve but for piece of mind id do it anyway, hell your under the car allready andrew Quote Link to comment Share on other sites More sharing options...
