Hard to clamp the lines as they are all hard lines or braided. When we clamped the lines before, actually dented the braid.

put the rubber hoses back on and do the tests if you are still having the problem then its not in a hose. If you are not having a problem replace one hose at a time until you find the offending hose.

Don't think it's the hoses, has to be a fault in the calipers maybe.

Just use vice grips and clamp all the lines. Take one clamp off at a time and check pedal before you take the next clamp off.


If you still have these wildwood lines fitted make some blanks to block the lines at the hard line on the chassis mount.
this is what you need if you can`t make some thing up
Edelmann Inverted Flare Plug Fittings 120300.
they are probably available from Aeroquip as well.
if you are carful you can use a 3/8" unf bolt for this and a O-ring   one for each fitting  you want a BS010 o-ring
put the o-ring in the fitting and nip the bolt down onto it . do not over tighten .
bleed by loosing the bolt.
any questions PM me for a contact number,
eliminate the cheep parts first.
you can try taking the callipers off each disc fit a block of wood in each 2mm smaller that the disc width and pump the pistons out and push back by hand to bleed air , then refit.
you can do this with caliper on, if you have an old set of pads. but don't pump the pistons out of the calipers

Do I crack the nipple to bleed air when pushing the caliper pistons in?

Yeah, after 2 months of trying, had to call it. Frustrating for a problem solver to not solve the problem.

Well, put the wheels on yesterday afternoon after adjusting the handbrake. Off the jacks and a couple of to and fro's in the garage to see what little braking effort I had. Brakes effective enough an inch off the floor. Hand brake was good, so took the car for a drive to bed the pads in. Pedal slowly getting better as the bedding procedure went on. Still spongy, but a better feel now. Still going to take the car down to Sydney Saturday to get it looked at, but appears to be getting better. Reckon it needs another bleed, but I'm over bleeding now, time for someone else to have a go.

I did not fit Residual Pressure Valves as the Master is higher than the caliper pistons

they are advertised for that purpose however they help with knock back problems and also bleeding  the system.

Sorry guys, away with work. Bedded the brakes in again, gravity bled the system, found a bit of weeping at the hose connections to the calipers, 0.020" gaps at the piston to pads which, after bedding in, starting to close up with the piston seals getting some use. Also raised the brake pedal at the booster 14mm. I honestly think the problem was not bedding in the brakes and then re-bleeding, as every time the pedal was getting better. Then dynoed at 254RWHP with 375 ftlbs of torque. Happy again.
