Thread: Oil in brake booster?

Just seems like it looses all its pressure at very slow speed.

Better order a master cylinder, better still, see if there's one in Perth ( assuming you're still there ) and get someone to fit it ASAP.

I have ordered the booster and a master cylinder as knowing my luck when I start touching stuff on a 14 year old car it will start a chain reaction of breaking stuff , plus I know the booster will probably fail sooner rather than later if I dont change it together.
We have another car to use so will use that till the parts arrive and I will do the booster as well as the master cylinder, and if the vacuum pump is leaking oil as bad as I think it is then that will get done as well.

If you’ve ever had a clutch master or slave cylinder go that’s how it feels with pedal sinking to the floor with no clutch release. Rubber piston seals fail and other tell tale is darkened clutch fluid. Not a regular occurrence on master brake cylinder but exactly same principle.

Well to update this , changed out both booster and master cylinder. No oil present anywhere in the booster or the vacuum line.
Bled the 4 wheels and wow what a difference in braking. I opted for the upgraded RRS booster from AF and I would go as far as saying the car stops better now than it ever has.
The change out wasnt that hard, well depends on what your frustration threshold is when trying to get the clip off the brake pedal pin... if only they put the pin in the opposite direction it would be a 1 minute job instead of a torch, mirror and a bucket full of swearing.
All in all not the worse job I have done on a LR but there always seems to be something that just makes it not a simple task. I never opted to change the vacuum pump as that just looks like a whole new world of pain. I did notice it is the source of my oil leak on the bellhousing tho.
Now to sort out my suspension/compressor issue.
