Problems after bleeding clutch slave cylinder

[A Ward]

Hi

I have just bled the clutch slave cylinder and have some problems that have occured since this was carried out - wondered if anyone else has come across this problem and knows a fix.

Basically while bleeding the circuit using a 'power bleeder' the brake fluid reservoir ran dry and it started blowing through with just the air pressure from the tyre used to power the bleeder (approx 14psi) - I realised the issue and went and refilled the reservoir then continued bleeding through until the fluid was clear with no bubbles, etc... then shut off the bleed nipple.

However on completion of the job and on trying the clutch the pedal simply goes straight to the floor with no resistance and remains there - something is clearly not right and I wondered if anyone has experienced this and could shed some light on it? Please note the clutch was operating perfectly before and I just carried the bleed out as part of scheduled maintenance.

I tried rebleeding the brake circuit as well but this made no difference to the clutch pedal.

All answers greatfully received - I have looked on the pcar diy and rennlist diy but they do not mention this happening at all - so I am a little bit at a loose end as to what to do next. Thinking of rebleeding the system and wondered if there are any other bleed points for the clutch system.

Many thanks

I am sure you will find the answer if you use Rennlist search. I remember reading this before but I don't remember the details. If you cannot find it you should post a question there and they will have an answer for you as I am sure people on there have done exactly the same. The best way to avoid that is to avoid getting air in the system - I was very careful to look at the reservoir and not let it run below minimum.

rebleed again and let it run for a while, theres also a bleed nipple behind the spare wheel.

Problem resolved - bled the clutch the old fashioned way using a bleed tube and syringe and two people (one pumping the clutch pedal - the other cracking the bleed nipple) - took aboout 20 minutes but the clutch is now working absolutely beautifully. Lovely smooth action and well pleased - plus as a bonus the fluid has been completely replaced due to the level of bleeding carried out.

Thanks to all those who posted. Cheers

Maurice are you sure the RS is like C4? I would have thought it would behave like C2 as it has not got 4WD system - I also was under the impression you need the Hammer to bleed C4 if you introduced air into the system but I may be wrong there. You don't need to use your foot to press the pedal - I used my hand and a gentle push was enough to move fluid out (had little plugs when I first changed brake fluid myself and wasn't bleeding with pressure so I pressed the pedal gently with my hand and it cleared the plug - this was to prevent the issue of going past the seal and damaging the brake cylinder if one used too much force by using the foot).
