clutch bleed

Hi Graham .
That's great , well done . It's so frustrating sitting and reading about this sort of thing . Being a retired motor vehicle technician I know how it must feel to work on something like this and not get the desired result . The TF and F all have the same issues as the trucks I used to work on . The problem is the size of the master cylinder vs the size of the slave cylinder and then you have the long pipe run that has numerous areas where air can get trapped as it snakes its way from front to rear . DAF trucks are a bitch to bleed if you are out on the road . Back in the workshop I fitted a spare master cylinder cap with a connector that you could blow compressed air through to push the fluid out and into the slave cylinder . When on the road I had a pipe from the cap that ran to a shraeder valve on the tyre to blow air that way, if not you could be stuck for ages at the side of the road.
Don't loose heart !

thank you, just waiting for my part from rimmer bros' then a bleed of the water system and i will be up and running again, the reason i changed the clutch flexi pipe is that i had changed every pipe on the car exept this one, put me off the road for four days as i sold my astra, it cost me £78 in the end, and he used a compressor like you to shift the air out of the master cylinder, well worh it, going to buy my own air pump so will not have to pay anymoe money out, thanks for your help,graham. :beer:

If you do buy a compressor , please be aware that the air you put into the clutch system MUST be reduced in pressure or you will blow the reservoir apart not to mention covering you and the car in brake fluid . There only needs to be a breath of air to get the fluid moving .

thanks is it around 10 psi

I think half of that would be fine . You don't want to have the fluid spraying out of the bleed nipple. It a question of trial and error.

thanks John,will take that on board :broon:

I remember years back watching someone pressure bleed the brakes using a bike pump. They had modified a spare reservoir cap by drilling a hole big enough for the valve off an old inner tube, pushed through from the inside and epoxied in. The non-return action of the valve allowed a little bit of pressure to be kept in the reservoir, but he had to pop back to to pump every few seconds.

It did work, but I had to wonder why having gone as far as glueing a valve in to the cap, why he didn't use the spare wheel as an air source... ?
