Hi again, my 3.1td Bighorns brake pedal feels hard resulting in very poor brakes. Big problem? Regards to all Joe.

Sounds like a vacuum problem it could be the pump,leak,blockage or servo.

Thanks Marky, any tips one the first place to check for blockage or leaks

Take the rubber pipe of the servo and check if its sucking plenty, if it is then its the servo, if not
Remove the pipe from the pump, if the pump is sucking then its a leak.

Bearing in mind that it could be something more sinister such as an ABS problem or the master cylinder itself.
But its best to start with the easy ones first Smile

Ps: take the ABS fuse out
