Thread: LRA Hydroboost Brake Upgrade Kit - replacement for vacuum pump assisted brakes

I have on mine from LRA, used a PSC racing hydro res with expansion tank and it works great

Hi All
I was thinking of adding front disc brakes and power assisted dual system to my 1976 series3 SWB. As there is no power steering on this model is it possible to fit Hydroboost upgrade ?
Generally am I on the right track to inprove the safe brakeing of my Landie.
Thanks
Geoff

Would just need hydro pump of some kind, either power steering pump or pto hydro pump?

Not possible. ADRs state that in the event of a failure of braking assistance ( such as the vacuum system, or the Hydroboost system ), there must be the capacity for four full brake applications before all assistance is gone. LRA is unlikely to ignore that.

Also, all braking systems must allow for unassisted braking as well, so there would be no loss of brakes even after the assistance is gone. The pedal would get harder, and the effort required would also increase, but the car would still stop.

So for those that have actually fitted and are running one, are they worth it for the pennies? Are the brakes significantly better?

How much is this kit?

Yes, Yes

its not from LRA but it works a great deal better than the standard brake system.

Where did you source yours from?


Have just purchased a D4 for the misses and been driving it a bit I've realised how lacking the D2a's brakes are, hence the revival of this. I think it's time.
