Bleeding Brakes
Posted: Sat Dec 04, 2021 9:26 am
Okay can I do this on my PX2 Wildtrak ?
On my previous Land Rover Discovery - ( It did not have anti-lock brakes ) - I used an old 4 litre LPG bottle I have for this purpose evacuated to a reasonable vacuum, around 15" of Hg - ( to achieve this I use an old fridge compressor I have as a vacuum pump; this is a common practice in the refrigeration industry to evacuate refrigerant pipe systems ) - This LPG bottle has a tap/cock on it and is then connected with a plastic hose to a plastic 1 litre container that I have for bleeding brakes, it has two connections on the screw-on cap, the second connection is connected by a hose to a brake nipple, this hose goes all the way to the bottom of the bottle.
All I had to do on the Disco is screw out the brake nipple a couple of turns, open the cock and the LPG vacuum bottle would evacuate the plastic bottle and draw brake fluid out of the nipple and into the plastic bottle, once the bottle had about 250 ml in it I would close the cock and top up the main brake reservoir and carry on with all four wheels until I had totally replaced all the brake fluid in the system.
I tested my Wildtrak brake fluid a year ago and it had a moisture content of under 1.5%, its now at 3% so it really needs to be changed.
My question is with the Ford anti-lock brake system can I still use this same method / system starting from the furthest brake ( passenger rear ) and working to the drivers side front- the nearest wheel ?
Do I need to have the engine running or just have the ignition on to activate the anti-lock brake system ?
Is there another way of bleeding and replacing the entire brake fluid ?
