Early 79 Clutch Flex/Hard Line

rjm65 · 06-07-2011, 03:46 PM

Clutch line #31 is starting to look a little worse for wear. The replacement made by FTE is currently on back order $43.50, and the alternative from Pelican is $158.50.

Has anyone tried rebuilding this line? Does it have a barbed end where the hard line fits into the hose? If so then maybe I can take it to a NAPA or a hose specialty shop and have them replace the flex hose part of it?

Can 30a and 31a be used instead or do you then have an issue with where the slave hard line #30 mounts up?

Thanks for the ebay link Bluemane, I noticed that a few listings popped up for the line recently. I was able to locate line last week from carpartsdiscount, took the last one they had in stock. Too bad Pelican didn't have the FTE brand hose in stock, because they had the lowest price bar none.

I was able to remove the old hose fairly easily, tight fit but I could just squeeze my hand in from above and work a 12mm open wrench 1/4 turn each time on the master side. I didn't want to chance rounding off the edges on the upper fitting of the slave hardline, so I removed the hardline from the slave side and then wiggled the entire line assembly out.

Putting the replacement hose back in was a bear. Probably would've been able to do it if I had someone from the bottom holding the hose and adjusting the angle, and working it from above to get the thread started on the master side. Just not enough wiggle room to really get the fingers in there. I thought I was going to be able to install it without having to make an access hole through the fender well, but just not possible if working solo.

It was getting late and I was just going to mark the area inside the fender well when upon closer examination discovered someone had beat me to it. There was a 3/4 circular cut about 3" in diameter. I removed the undercoating that had been sprayed over it and bent the flap back. I was able to work the fitting into the master with ease.

I opened up the bleed and let fluid run. Did a preliminary bleed using a mighty vac handheld. Pedal would stick to the floor. I pumped the pedal a few times and noticed pressure building up. Ran about 10 ounces of fluid through the system using the handheld vac pump.

If I have any further issues with bleeding the clutch, I'll just run a hose from the left front caliper bleed to the clutch slave and use the brake master as a reverse power bleeder, works every time.

I'll post some pics up later.

Here's the old hose:

New replacement hose:

Here's the access cut-out someone had previously made. Instead of doing a full cutout, they left a small section that allows the flap to be bent back and down.

Once everything was tightened up, just bent the flap back into place and sprayed a little undercoating to seal everything back up.

Not as bad a job as I had expected, went pretty easily actually.
