just a quick update, redone calipers, new brake pad, new brake pipes, the rubber pieces that connect to the calipers, still no luck. changed the master cylinder again but this time with a 1.3 toyota corolla booster wit the master cylinder and problem solved, don't know if it was the standard brake master that didn't have enough travel for the disc brakes but all's good now.

Just an update, installed new flexible brake lines, had to modify a set of different discs since we don't get the stanza discs here anymore and new brake pads. solved the problem, turns out the discs was too thin and when i brake hard, the pistons goes out too far and gets stuck. thanks for all the feedback

It will i had the same prob. with a 4door i had, Just to be on the save side get a new kit for the calipers, and take a compressor and blow the pipes kleen from the master, incase something got loged in a steel pipe.

I don't think you wanne do it all again?
best of luck (Not nice work, Brakeflued)

kiri i also bought new brake line, you are correct in saying that i used the old flexible lines, but that is being replaced as well. so hopefully problem will be solved

Riaan, A brackbooster is a good option But your problem is the brake lines. You replaced the strats with the flexible pipes that came with it? The pipes are periched on the inside and thus work as a one-way velve, it is worse when the brakes are hot from stopping hard. When you brake flued goes into the caliper but the pipes prevent it from going bake thus stopping the ute.

Replace the flexible bracelines in the front, and your prob will be solved. The new discs and pads help this prob to be worse also.

my problem only started once i fit the stanza struts in front, the drums would not stop properly even after servicing them.

My brakes builds up in front, the rear brakes are not not working at all atm because they are finished, but having them redone today, so i guess it can't be that valve. i'll keep you posted when i get the ute back from the brake shop

Is this thread of any help?

yes it's the drum brake cylinder, but a new one. can you post a pic of the line pressure valve? i have no idea what it looks like and if i have one. i took it in for new discs and brake pads, new linings at the back and scemeing the drums at the back. hope it fixes the problem...

yeah check that it doesnt have a residual pressure valve, even though ive never removed one and my discs have always worked fine

but also check that your brake pedal have some free play when its not pressed, otherwise it will slightly hold the brakes on when your foot is off
