Brakes Problem
Just replaced the master cylinder after 2 mechanics & myself tested the pedal and found that if we keep our foot on the pedal, it will eventually go to the floor.
Well, with a new master cylinder fitted, I have exactly the same problem. Push hard on the brake pedal and leave your foot on it, your foot eventually goes to the floor.
I've got new extended rubber brake lines as I have a 3" lift.
There's no loss of brake fluid.
Is this a Patrol 'thing'? I wouldn't have thought so.
Thanks for any help.

How old is brake fluid? Is engine running (vacuum for booster)? Drum or disc brakes? Rear proportioning valve (load sense)?

Bleed / test the LPV. Every mechanic (even brake specialists) miss that.

You can sometime end up damaging the master pump by manual depressing of the brake pedal to bleed the system(pressing it all the way to the bottom), but that usually happens with a used master pump, where the seals are already weaker.
How did you bleed the master pump, etc?

I don't know if the wagons have LPVs?

I let the mechanic do it.

Its a Patrol thing. I have changed to braided line, new cylinders and rebuilt calipers and it still does it. I wouldn't be concerned about it.

Bloody hell, that's not too brilliant.
The other week I was travelling home, a guy towing a Dunny door on a trailer got into trouble coming down hill (this is 100kmh both ways, country road), I was going up hill. He fishtailed until the trailer began to steer the car, he crossed both sides of the road and a bit more, I planted my foot on the brakes and the damn pedal just kept going to the floor and I was getting closer and closer to this guy.
Anyway, I'm still here.
