We actually replaced the master cylinder with a used one and still had the problem. Bought a new one and while we were doing it, did the Servo too



(Servo was replaced with a used one)

Pretty sure it's the same bud.

I had a very similar problem when fitting my Wilwood brake kit, turned out the bleed nipples has a tiny leak so air was getting in from there. Doesn't sound like the problem on yours though as they worked fine on the car before.

Make 100% sure no air is getting back into the nipples on the "upstroke", put some clear plastic hose over the end of the nipple if you haven't already done that?



Do you mean that with your foot on the (soft) pedal it sinks slowly to the floor....feeling a bit like a shock with no spring or a gas strut that's run out of gas?

Tried that already mate.

I've just been around checking for leaks for the last hour to no success.

Changed all copper washers on flexi hoses.

Even put some thread tape on the nipples.

If i pump the pedal repeatedly it will go hard

But if I take my foot off after pumping then go

Back to the pedal it will go spongey and will push straight to the floor after only

Leaving it for literally 5 secs.

Cheers for replys. Hope we can get to the bottom of this

Didn't imagine I'd be bleeding my brakes on my bday lol
