Brakes

My sc 3ltr turbo has an extreamly soft brake pedal it goes about halfway to the floor is effective (can lock all four wheels) the mastercylinder has been replaced several ltrs of new fluid flushed through passed MOT without comment, but the soft pedal does not instill much confedance my Landcruiser in comparesence has arock hard pedal and neads only light pressure to bring it to a stop.Any ideas please or is this normal.

I find a similar thing comparing my Hiace and Prado.

How are the rubber lines?

Could still have some air in the line.

Have renewed the rubber lines and bleed the air with two people have been bleeding brakes for no less than 50 years would you believe and am still mystified .

I'd have a good hard look at the rear drum brake adjustment, unless they are perfectly adjusted (and ideally bedded into the correct shape) you may find your pedal travel is take up mostly with moving the shoes closer to the drums.

To test I guess check that all brakes start working when you start pushing the pedal: the wheel(s) that still spin maybe the ones with problems.

I had this with a Peugeot which got it's hub carriers bent by the monkey pressing out the old hub bearings, it meant that the front pads hit the disc at an angle and took ages bedding in. The bedding in period had lots of travel and planning ahead, but once bedded properly worked fine.

Perhaps a simple MOT brake test might show up an issue?
BTW I have the same van as you, I only have to look at the pedal for it to pull up sharply, that's with bedded in rears and new front pads and discs.

Normally, drum brakes should always touch the brake shoes a little bit, even when not braking, just a very little resistance which should stop the wheel spinning after a while (when spinning the wheel by hand). This means it is very close, and there shouldn't be any play (or delay) when pressing the pedal.

Another thought, is the brake load balancer on the rear working properly?
Although thinking about it, it shouldn't have such an effect on the brake pedal being soft.

There is a bleed nipple on rear brake balancer and has been bled however not sure if it needs adjustment and or what the settings should be that is position of lever in relation to axle body measurement any ideas.
