hi fallas im bubbas dad ive raided one of the boys accounts to ask this im doing up a mini k for one of my little ones as i pumped fluid into the bags the back ends way to high ive let fluid out which is a waste of time .any wisdom of how to get the back down....... thanks

Has the back got the springs in there that go from the suspension arm to the top of the arch?

springs are in good nick not over sprung and fixed solid to the body

to let out fluid lowers the front but the back shows its under body like a girl wearing a mini skirt

You can put up to a 5mm spacer washer on each front strut, this lifts the front up relative to the back.
What colour are the rear springs- later ones are orange (stronger) and hold the back down better.
Note that it's normal for the rear to be a little higher than the front on a hydro car.

Hi bubbas dad, are you able to post photos?
I had a similar issue with my CooperS and I ended up putting a small washer between the ball joint post and the hydro bag. I can't remember the exact thickness of the washer but I think Mini and Moke sell them? This leveled out the car and it has been stable since.
Are the hydro bags the original ones from the car?
Is the rest of the suspension standard or have you changed any thing?
Do you know what the pressure is you are pumping up the fluid?

Hi
are you using a proper hydro pump ?
did you evacuate the system before pumping it up ?
Mite sound silly . But . put the rear up on ramps before you pump it up , the front hoses are the highest point of the system and this is were air can be trapped, pump it up and let it down to expell the air in the system ,once you think you have got the air out , put on level ground and adjust the ride height . once all the air is out of the system , if it is still low at the front you may need to add shims to the front . Hope this makes scence

Mark

this is my 2 cents worth also - sounds like there is air in the system.

Hi Bentons Dad,

I live in Orange and hope to have my now long term project going soonish and might come down your way to hopefully cruise with some minis one day

One other possibilty may be that you have Cooper s bags in the back? More rubber, I think there is about 1/2" difference in the depth from the top of the displacer down to the rubber between Deluxe and Cooper S displacers?

My wasa`Matic is the other way round- I have GT bags in the front and Matic/Mini K ones in the back, and with 2 full tanks it sits level.

If your rears really are S ones, I'd swap `em to the front.
