Self service garage

You can get this sometimes with new jacks (don't know how old yours is Malc.) but you can have a bit of air in the system from filling and transport which takes a few uses to get rid of, especially if the oil get aeriated. Always best to let the weight onto your stands anyway, takes the stress of the jack.

@Mazza all too common these days with cheap jacks. Just proves that you should never work under a vehicle that's only supported on a jack. A lot of cheap jacks will lower without any weight on them just as yours has if there is a gap between the car and the jack now.

It is new so thanks for the info Tony
 
Picked up the bracket plus the 3 nylon nuts that hold the undershield up . They were not in the best of condition, due to being overtightened at some time.
One thing I did find this morning, the Halfords low profile trolley jack, has dropped over night. The car is on axle stands, but I had the trolley jack with some 4 x 2 under the sill, between the jacking points Not really taking any weight but just as a precaution. This morning there was a 1/2 inch gap between the wood and the sill, despite the release valve being tight. Not too impressed, but is this normal ?

I bough a Halford Jack once.
It’s now in the bin!
Take it back while you can, I wish I did!
 
Most probable reason for the jack failure will be manufacturing fault, ie the jack cylinder is probably not true circular and/or inferior quality rubber seals. Most still use a cone type seating on the relief valve, which is fine as long as it's made from a good quality hardened steel. They are susceptible to overtightening which damages the cone and hence you lose pressure.

Much the same as a bleed screw on a brake callipers. They only need nipping.

Thanks to all for your comments.

I have checked and cant see any fluid leaks, so will use it but never work under the car without axle stands.
Which will be in the morning now when I reinstall the new exhaust bracket.

No I’ve 2 trolley jacks and I’ve left the car up on both sides and the don’t move at all, But never just trust them I always back it up with stands even if I don’t put the weight on the stands they are under.
 
All put back this morning.
Took longer that I would have thought.....but still aching after playing football yesterday....which we lost :(.

Top bracket cleaned and painted, bolts cleaned with a trace of copper grease and reassembled.

All this for a shiny new bracket that is never seen...

But does anyone recognise this .....It was being used instead of one of the washers ( ref no. 3 in the exploded view above) I replaced it with a normal washer as diagram.

That plate is part number 7, which means tomorrow morning I have to get back under the car, take the undershield off again and fit it back on the car. :banghead::banghead:
 
Sorted !!
