It’s a Far Horizon Tuff Track Escape. Love it. Very happy with it

Dreaded restricted performance warning popped up today. Went away on restart and hasn’t popped up again yet…

I suspect the inlet manifold on the side I haven’t had replaced yet but haven’t had the heart to read the error code/s yet. A job for tomorrow

Or intake plenum split. I had that. Split where the Y element meets the throttle body.

This and “Normal height only”


Vehicles been sitting for 8-9 days and the dash cam helped pull voltage down below 11.9v

A couple of drives and it was gone. Now on charger.

Problem will be sorted soon to counter the lack of daily use.

Was back with a vengeance at Snowtown last night.
Final run into Adelaide at lowered height was interesting!

Dropped in to see Basil135 and an hour underneath saw the compressor sorted for now.

New one on its way.

Bugga!

All good… running for now, locked in std height.

Picked this up today and dropped in. Fits like a glove.



Also picked up my ARB Linx system and the gear to do my stereo upgrade has arrived.

Watch this space!

Fortunately the job is brilliantly covered in the Shane Shed videos and not as scary as it first looks.

Has anyone worked out a catch can or is 14 years a good enough run for any booster?

New RRS booster fitted and have brakes again. As the ShaneShed video shows you can safely flex the ABS unit and master cylinder well out of the way to change out the booster quite easily without having to spill a drop or bleed brakes as the workshop manual suggests.

The old booster had definitely failed and shows evidence of oil inside but was by no means carrying a lot of oil.

Removed and checked the vacuum lines and they were almost squeaky clean and NRV function is perfect. I didn’t touch the pump as with engine running and pipe disconnected there was heaps of suction.

Since the vacuum pump sucks the only logical explanation is that oil vapour sneaks past the NRV with engine off. It’s hard to imagine otherwise how oil gets in there.

I know these days replacement parts are often "pretty affordable", but as an FYI, but I've had these guys rebuild "unobtanium" boosters for me along with rare and old master and wheel cylinders : Home - Perth Brake Parts
Haven't used them for Disco parts yet however.
