Hey guys as the title says My clutch lost all pressure last night. Iv just replaced the slave and the master in the bay. I'm trying to bleed the line but I can't get any pressure to push the fluid through. There is no resistance in the Peddle. I'm also not leaking fluid anywhere. What's going on ? Any help would be great thanks
The system is notoriously hard to bleed... Make sure the piston on the slave cylinder is pushed all the way in before you start. Fill the reservoir. Open the bleed valve on the slave and wait for gravity to do its thing; close the valve once fluid comes through. Refill the reservoir. Open the valve near the HICAS actuator and start to bleed from there. Refill the reservoir. Bleed the slave cylinder. It's a bugger as the lines are long and bendy but you should be able to get it. Worst case fit a single piece line and never worry about it again
Thanks rob I can get a steady flow coming from the nipple on the slave but I can't get anything coming from the nipple in the bay ?
I just had my phone on record under the car and the needle on the slave isn't moving when I press the clutch in and out. Is that because I have no pressure in the line ?
Had the same issue Found that the piston was at full extension and would not retract. Had to pull it off and get the piston moving again
hey You're not relying on gravity to give you fluid from the nipple at the top are you? bleed the top the same way you would brakes, peddle to the floor, crack the top bleeder and then re-tighten before releasing the peddle. repeat this process till you get fluid through. Don't let the res. get low. ( 2 person job) Hope this helps
Your best advise... As mentioned above... Change that line to one piece line from master to slave... It's a pain in the ass job, but it's doable... Get a hard wire "something like wire from old cloth hanger", to make template out of it. Make a route from master to slave... Once bend it in the shape. From your local brake shop you can purchase 1.5m of steal line for few bucks. If you have flaring tool, you just need to bend the steel pipe in to the shape of your template and flare the ends. If you don't have flaring tool, go and get a cheapest brand ... It will do the job... After that bleeding is easy as...
Forget about changing the hydraulic lines to a one piece unit. If you really want to simplify the bleeding procedure & this also applies to the brakes, replace the OEM bleed nipples with Speed Bleeders, then you can do it without any need for a helper.
Iv passed 750mm of fluid through the lines so far so I'm pretty sure there is no air in the lines. Still struggling to get any fluid coming through the nipple at the front of the bay
If you've flushed 750ml through the lines & it's struggling to come out of the nipple in the engine bay, then the fluid must have come out of the nipple on the slave cylinder. If fluid isn't coming through the nipple in the engine bay, there must be air in the pipe. You have to continue the bleeding process. You could connect a hand operated vacuum pump to the nipple, that'll pull the air out. Or you could pressure bleed via the master cylinder, that'll push the air out.
Yeah a lot came through the slave but even with that shut and then pumping the peddle with the bay nip open nothing would come through Could it be blocked. I think I might have to get someone out to bleed it properly Iv done everything I possibly know how to do. One more thing I can hear a hissing noise from the the master when I push the clutch in Is that normal. It's like the sound of the rod pushing and something happening but should you be able to hear anything ?
If the engines off, you may be able to hear the cylinder operating. Is the fluid in the master cylinder dropping as you attempt to get the air out of the nipple in the engine bay, or remaining constant? Are the replacement master & slave cylinders brand new, or used?
I'm not saying that you have split hard line. But there is a brass T section joint "driver side somewhere below the turbo" from which you can remove that bleeding line that goes in to engine bay, and fill that empty hole with some bolt, third line out of the T section goes to the slave cylinder. That way you can make one piece line out of the existing line... However that brass T section is really hard too reach...
