Clutch hydraulic line circuit
Clutch hydraulic line circuit
This weekend I installed the clutch pedal, clutch master cylinder and portions of the clutch hydraulic line in preparation for a tranny swap. Let me tell you, there is nothing more uncomfortable than working under the dash of a car.
Anyway, the clutch hydraulic line circuit has one small diameter line that runs from the master cylinder down to a junction box, then on to the slave cylinder. There is a second, larger diameter line that comes from the junction box and coils down, then back up and terminates up at the strut tower. There is a fluid bleed fitting at the terminus. I am trying to figure out what the purpose of this second line is. It looks like it may be a pressure accumulator because of its larger diameter and the way it coils around, so that the hydraulic circuit isn't overpressurized when you press the clutch pedal to the floor.
Anybody know for certain?

I spent a few hours trying to get that section to fit in, then said screw it, modified the connector, and took it out. I just have one hard line and the flex line going to the tranny. no problems so far, two months later... knock on wood...

Yep, after spending about 2-3 hours trying to make it fit, comparing it with another 5spd, I found the line from Nissan didn't quite match up with the bends in a stock 5spd. After bending for a while, I just said forget it, used the two short hard lines, the block with one hole sealed, and the short line to the tranny. Works great.

Ooooo.... so you got rid of the hard line that coils? We had to remove the ABS actuator to put that in!

I dont know why you guys had problems with that coil. I installed it on meccanobles car and on mine. I really dont see much purpose to it, but that doesnt mean it doesnt have one. Anyway, I bent mine out of shape until they fit. it looks funny and all over, but I don't care, it works and its there. ABS is definitely a pain. I agree, working under the dash with the steering wheel in your crotch is not comfortable (unless you're a girl, maybe). The worst part is definitely drilling that stupid hole in the firewall. Everything else is just work.

Interesting.... I tried getting that coiled line in and couldn't and decided there wasn't enough room because of the automatic transmission. Also, it looked like I was going to have to disconnect some of the lines going into the brake master cylinder in order to get it snaked in there.
Maybe I'll just leave it out instead.
