I have a 95 Hi-lux dual cab deisel with really losy brakes, especially on the rear, with the rear wheels jacked off the ground and the engine idleing in first gear i can push on the brake pedal as hard as possible, and all that happens is the engine will slow slightly, if i pull the handbrake on the engine will stall.
So far i have new rear drums, linings and wheel cylinders, new master cylinder, have tryed a 2nd hand proportioning valve and flexible brake line and have tied the proportioning rod up to simulate fully loaded vehicle, still no rear brakes. I noticed that this problem has occurred before in the forum archives but no answer was found, can anyone help

remember that the rear has only 40 % braking and the front is 60% , this to allow the vehicle to stop withought the rear end locking up . Does the vehicle seem to stop ok on the road ??? do you have a spongy pedal ????when you crack the rear brake line for bleading , do you have pressure??? answer these questions , all we will start eliminating items Craigs hut 2003

The vehicle has never stopped well since i owned it, does have some pressure when bleeding with plenty of flow.
Brakes pedal is hard, but if i disconnect booster it goes even harder

Sounds to me like a pinched/squashed brake line, seeing as the handbrake works and everything else is new...if its not pinched, check that it isn't blocked, maybe a previous owner got a resevior full of mud or dirt, and its now in the line. I think water in the lines would cause corrosion which would certainly block it up. Does it flow easily when you bleed the brakes? Any discolouration of the fluid?

Good luck...

Mate has told me that he fitted slotted rotors on his GQ and its made a world of diffrerence, and the price was right.

Apparently there are 3 different materials they are made of to, with the better of them $100ish each.

Thats my one of my next investments as soon as I find someone who can get them at trade cost!
