Defender 90 brakes

Hi all
I cant find a definitive answer on the forum, so here we go.
I have problem with my 90s brakes, I have changed the rear callipers, and still have a soft brake pedal every 4 or 5 presses, so, I've just changed the master cylinder, bled all calipers, twice, The pedal is even better now, but it still goes soft every 4 or 5 presses.
What am I missing, I've used a eezibleed twice, the rear discs are worn and could do with changing but I can't understand why the pedal goes further every 4or 5 times ?.
Oh and There new pads all around.
What's the answer ?
Regards to you all

i read something recently on the forum about changing something in the vacuum pump or servo to improve the brakes. I cant remember exactly but hopefully someone else comes along and does remember

I have started the engine with my foot on the brake, the pedal moves down, which suggest s the servo is working

Have you checked all your pipes for leaks.?!

Don't know how old/new your fender is. Is it a standard brake set up or does it have ABS? Have you checked for loose wheel bearings / warped disks (they could be pushing the pads / pistons back in the calliper so some effort is being wasted pushing them back out before they bite).

I had a problem like this with my disco when I fitted the new callipers upside down

Sounds more like air in the system to me, check all your brake pipes.

I have no fluid lost ?

That doesn't necessarily rule it out, in fact it's quite possible you are losing such a small amount of fluid that you barely notice that it's gone. The problem your describing suggests that there is air in your system, if your bleeding it and it then once again returns, this would imply it is entering the system between the servo and the calliper. Personally, I would start at the very beginning and trace your way forward.

Good luck mate

Mine did this and it was the wheel bearing as mentioned. It was obvious when jacked up, you could wobble the wheel.

Thanks, thats the next on the 'check' list, if it evcr stops raining

Bit of a late update, it was the font wheel bearing, all done now.
you live and learn.

thanks for all your help
