During my engine pull to replace the clutch, I had to disconnect 2 hydraulic lines to facilitate the separation of the engine from the body of the car. I inadvertantly removed the clutch fork slave cylinder line also, forgetting that I just needed to pull the slave cylinder out, not disconnect it. Anyway, with three open lines, about a pint of brake fluid was collected. Now the engine is back in and all I have left is to bleed these lines. I noticed that little if any brakefluid is missing from the brake fluid reservoir. This makes me wonder if there is an actuator that needs to be opened with the hammer to properly bleed these lines. If not, is there any special process other than pumping the clutch manually to refill the lines with fluid? There are 3 slave cylinders that need to be bled. One that is perpendicular to the trans (passenger side) and is at the lowest point. The second is attached to the driveshaft tube and is at mid level. The third is of course my mistakenly pulled clutch fork slave cylinder and that is at the top of the trans, therefore the highest point. Is there an order that these should be worked on?
I'm so close to getting back on the road!

Dear Von,
I highly recommend you carry out a full bleed of all systems in accordance with the Maintenance Manual. Short cuts are really not worth it. Do it properly once and you have no more troubles.
You have to bleed the hydraulic clutch lines, they are hooked via the brake lines which is hooked to the traction control.
Believe me it is worth the little extra time and cost now.
Ciao,

Adrian, I actually just got the full system bleed with the hammer 2 days prior to my clutch job. What a bummer to have to do this again. I do want to get it properly done, again. What I ask now is whether I have to tow the car to my mechanic or can I do a partial so at least I don't have to deal with a tow truck and driver.
It's funny that my mechanic did not mention that I should wait to get the brake system bled until after the engine pull. Maybe it's funny to him...

Dear Von,
I am afraid you have asked two questions I cannot answer except to say if it was me. Based on my knowledge of waht can happen and not just with 964s but 928s as well, I would for safety sakes stick it on a flat bed.
On the second question I would be kicking that mechanics backside and making him pay for this. That was unfair from him to do this if he knew the engine and gearbox were coming out.
I would hate to see you damage your clutch or gearbox or worse, have no brakes on the way there.
I am by nature, when it comes to safety and economics a conservative person and I do not want to give you answers which in worse case scenario would cost you even more money.
However in the end it is your 964 and it is your decision,
Ciao,

PS: If you tow the 964 make sure you four wheel tow. That means all wheels on the deck. Only recommended for distances of less than 50km.

Von, for safety's sake, I woud agree that the flatbed is best. Having said that however, when I first got my C-4 a couple of years ago, I stupidly treated it as a C-2, and changed the brake fluid in my garage. There was hell to pay to get any brakes back, but I eventually did, folowing the manual (if you can understand the bloody thing) I was not totally happy with the state of affairs, and since the closest dealer is 200miles away, I drove the car there, and had them bleed properly. I will NEVER open this system by myself again.

I think you will need to have the system Hammered. I am guessing the other two lines you disconnected are the tranfer lock actuators, my name, for the traction control system. As these work off the high pressure side of the hydraulic system they need to be opened electricaly by the Hammer to allow bleeding.

I don't think these lines need to be broken to remove the engine the procedure is to remove the actuator with the line intact.
