Hi All,

I had the rear brake proportioning valve situated on top of the rear axle sh1t itself on my Landcruiser ute last weekend. Fluid squirting out in a big hurry, 2 or 3 pushes and the reservoir was nearly sucking air. After spending a couple of days trying to find a second hand one I ended up getting a new one sent up from Brisbane today.

My problem has been trying to get all of the air out of the hydraulic system. After sending 2 or 3 litres of brake fluid through the system I still do not have my nice hard pedal back but only have a spongy pedal that is sitting a little bit lower. The rest of the brake system is relatively new and in good condition.

Any idea's from the experts??????

What brakes does the 75 have disc/disc or disc/drum?

You need to bleed the nipple on the proportioning valve, then the rear brakes, then the front from memory.
you may have to get it pressure bled if you can't do it manually.

Hi Peter,

It is a disc/drum set up. The nipple on the proportioning valve has been bled but I think I may have to go somewhere and get it pressure bled as you suggest.

Thanks mate for your reply.

Hi you need to look for any high points in the brake system and bleed there first, it sounds like you have air in the mastercylinderso bleed that first .
Tip ....Before you start bleeding give it a good pump on the pedal first as this will help.I used to do this for a living many years ago and I dont think that brakes have changed that much.

Good luck
