[urq] 83 urq Brake issues - where to go now?

[JP]

I have an 83 URQ - with brake issues.

 

So originally the problem was the pedal was hard.and the brake light would
come on and yes, braking was not good to say the least. 

 

So I checked pressure at the top switch both to pressurize and after venting
the pressure, the switch was fine, but I felt the pump was not providing
enough pressure so I switched out the pump.

 

After that the pedal did feel better but the brake light on the dash was
still on.

So I proceeded to replace the bomb. 

 

The brake light went off for about 3-4 mins (running the engine at idle)

 Pedal felt great, no light, even pumping the pedal fast, felt good etc.

But after about 5 mins, the brake light came back on? 

When I move the steering to either locked side (full left or full right) the
light goes out, but returns comes back on when not full left or right. 

Then when looking around in the engine bay I touched the pump and it was
pretty hot, I followed the lines and the Brake Servo and lines too were also
hot! Is this normal? Anyone have any ideas on what I can look at? Or what
might be going on?

 

Any help would be greatly appreciated!

 

Thanks
