Outer Limits 4x4 Board

I'm having trouble with bleading the brakes. I have installed GU diff's and brakes in my GQ (not that I think that should matter) and having trouble getting pressure on the peddle. It will pump up and from the fluid dropping in the resivour I think its the front pumping up. If it sits for a few moments the level rises again. I have tried bleading heaps of times but I'm thinking it still has air in it. Could it be anything else? Is there some trick to bleading the front?

Cheers

are you bleeding ech section of from master cyl down to the wheels one at a time, or just bleeding straight from the calipers first off/??

make sure u bench bleed the master 1st, then bleed from the closest wheel (drivers front) and work your way back to the furthest.

I have just been bleeding the calipers. What does bench bleed mean?

Cheers

Bleed the left rear, right rear, proportioning valve, left front and then right front.

Thats how i've always done it. Start from the furthermost caliper/drum, then work your way to the closest.

I do a bulk bleed first, then a pressure bleed next, followed by a final pressure bleed.

Make sure your proportioning valve is open too!

The little swing lever needs its adjusting bolt screwed all the way in, which will in turn fully open the proportioning valve. A lot of the "tighter" 4wd enthusiasts (including myself) do this when we lift our cars as opposed to buying and fitting the special brackets for lifted cars.

Thanks all. Have fixed the problem - my fault. Its been a long project. When I fitted the calipers I fitted them to the wrong sides. That left the bleed nipple on the bottom, not on top.
