What does it mean when your brake pedal is hard to push?
Vacuum – or really lack of vacuum pressure – is the most common cause of a hard brake pedal, and therefore the first thing to look at when a hard pedal is present. Any brake booster (whether from Master Power or any other supplier) needs a vacuum source to operate. When this happens, the pedal gets harder.

Why is my brake pedal sinking in my Land Cruiser?

On inspection the inside of the cylinder looked mirror smooth so I ordered new seals for the cylinder (3 working days from Johannesburg).
What to do if your Land Cruiser has spongy brakes?
You could also try bleeding the master cylinder of course. Undo the unions on there and push the pedal with finger of the outlet (gently, mind your eyes) then hold finger firmly in upstroke to suck fluid back into the cylinder from the reservoir. Also got to suspect the seals on the front cal, I gues. Don’t like the adverts?

Open the bleed valve about a half turn, and have your partner depress the brake pedal. Once the flow of fluid slows, close the valve. Have your partner pump the brake pedal, and then repeat the process.
