Hi, got a bit of a problem in the mornings.  Some mornings, but not all, the brake pedal is rock hard, usually it eases off within a few seconds and all is normal, but if it is colder it takes longer to start working.  Yesterday it was a bit nippy and I ended up going about a mile before it sorted itself out.  My mechanic friend thinks it may be the ABS system but I thought I'd ask here before trying anything else.  It's a 54 2litre diesel.  If anyone has any ideas I would be very grateful, thanks.

"Understeer" is when you hit the fence with the front of the car.
"Oversteer" is when you hit the fence with the rear of the car.
"Horsepower" is how fast you hit the fence.
"Torque" is how far you take the fence with you.

I'm fairly sure the servo is OK, I've done the checks and it seems to work well.

Usually this is the brake servo, check that the vacuum pump line is not holed, diesel have no depression in the manifold and require a vacumn pump. The line from it has been known to chaff through. If that is ok then you are loosing the vacumn overnight from the diaphram in tge servo, small pin hole maybe. Needs to be sorted

I second this. Check the vacuum lines!
