So this is a struggle.
I fixed the three amigos around 10 years ago with the bypass mod, but it went wrong again, this time the error was a pump fault, and sending the ABS modulator away confirmed it was faulty and non-repairable.
So I got a fully reconditioned unit, fitted that - sorted the problem, but I now found the brake pedal would slowly go to the floor.
So replaced the master cylinder with a new one, which has sort of fixed it.
However there is a new problem, press the brake pedal and it goes almost to the floor, pump it once or twice and it goes solid (well defender solid anyhow).
Sit there several seconds to a minute and again the cycle repeats - pedal goes to the floor, one or two pumps and back solid.
Importantly, the vehicle is not moving, just stationary whilst we find the problem. A few years back it had stainless braided hoses fitted all round, it had the front pipes replaced and new pipes all around at the calipers.
It has been pressure blead (several times now) including power blead through the modulator, no leaks anywhere.
I can't find how to solve this at all, the master cylinder has been changed, no driving, so not wheel bearings, when it goes solid, it's more solid than ever before, all new brake fluid, no air bubbles and the fluid isn't going down .
Totally stuck
Any ideas guys?
