Yea, I'm thinking the aftermarket needs to come in for the rescue. A direct replacement for the line and delay valve assembly, with a hard line or braided stainless steel.

I'm going to try to source another line and see if I can drill it out.

 

[BREADwagon]

I just bought another one (the revised tube with delay valve). I'll try to take some detailed pictures and see if you can drill out the valve or machine a new fitting that replaces the valve.

I was driving around some twisties last night and I must say that the clutch line didn't bug me in the slightest. Quick heel-and-toe double-clutch downshifts are no problem - I no longer notice the new PTL as I did when it first went in. It's seriously not that bad.

There's a lot of moaning and *****ing about it, and it's scaring a lot of people away from the TSB because of it. I was worried about it, needlessly as it turns out.

Give it a few days, it gets better.

Agree the clutch is not that bad after tsb.

I am wondering why you are both double clutching and heel toe shifting? Also, what mod did you do to the accelerator pedal?

Had my TSB done last week and I think the Clutch is an improvement with the new line! Clutch is much more linear in engagement and easier to modulate.

 

[BREADwagon]

I don't know, maybe the tech didn't bleed it right. I find that the engagement point is the same, and the linear progression of the engagement is the same under stop and go conditions. However, under spirited driving, I feel like it gets in the way. Rev matching isn't as smooth as before.

For those of you who wish to modify your clutch line I have attached a few photos of what you need to do. The restriction for normal driving is not an issue for most, but for me its far from what I'm use to. I tend to drive conservative most of the time, but when I'm push it, I'm very aggressive. I feel that with the current clutch line my clutch will need to be replace more often then I would want. With more power, this restrictor will cause the clutch to slip when shifting aggressively, its already happened to me twice.

As you can see in photos, its a simple process to remove the restrictors. There is one on each end of the line. The one end has a clip and it pulls apart, the restrictor is easily removed. The other end has to be drilled out. You will know its drilled completely when the spring and very small restictor comes is out. The ends look like Mustangs, and there are braided lines on the market for Mustangs, but I am not sure there are exactly the same. Maybe one of the vendors here can work on getting a line made up. Once the restrictors are removed, there still a little restriction due to the inside diameter of the line, but for hydraulic fluid it should be fine. When testing with restrictors in place it was evident the restriction was more than it needed to be.

I have not yet installed the new line, I hope to have it in by the weekend and will give a report.

Good luck with that , it might not work due to the fluid now having to fill up more "empty space " that was occupied by the restrictor , but do it and lets see what happens , I was going to do mine when I replaced my line but the restrictors don't bother me , anyway that line is cheap enough to be experimenting with

Just what I thought would happen eventually. Instead of fixing it, they upped the nannies. The performance crowd doesn't care for that and will remove it.

I have a feeling that won't matter very much. Subscribed to see results of how clutch feels after mod.

 

[NES ST]

I already did , I'm curious to see the results , I was going to do it myself but I don't have the time or the will to do it

The line is the only thing being modified and it is not the opening at the very end, therefore the amount of fluid being put in by the master and leaving at the output will be the same as it was before. It will either let you dump the clutch or it won't. No matter what, the clutch will be able to engage quicker than it did before.

I had mine done last week and i am in the group of people that actually like it, it took a little getting used to at first but now i can speed shift the hell out of the thing and row through those gears like a madman and it adds a nice level of smoothness no matter how fast you rip your foot off that clutch pedal, that part along with the mounts and the power feels soo much smoother and now there is no wheel hopping even if i do fun burnouts in 1st gear ( which sounded like the a transformer having an orgasm before i had the tsb done to it) and something i didnt think would be affected by the t.s.b was how different the shifts feel now, they fell a little bit more mechanical and less rubbery. All i can say is that the t.s.b definately makes it a more fun car to drive

 

[ugly duck]

I am wondering why you are both double clutching and heel toe shifting?

Why not? I double clutch for every downshift and heel-toe for downshifts while braking, when I'm braking hard enough to get any kind of firmness from this dishrag pedal that is. Yes the tranny is triple syncro'd - I'd still do it if there were 14 syncros on each gear.

Also, what mod did you do to the accelerator pedal?

None yet. When pressing hard on the brake it's not too bad with wide shoes. I really want them closer together though. One day when I can get near my garage...

@Yo Ken

YES! That's exactly what I was hoping we could do. Why is the connection at the slave a "T"? Is that were you bleed the system from?

Speaking of which, how are you going to bleed the system?

Yes, that's were you bleed the clutch. There is a 7/16's nut to bleed the system on the end. I use a power bleeder from Motive Products, and it makes it a one man job. They are not expensive, it's a good tool to have in the garage. I will takes some pics when I install the line tomorrow and post a report on how it all turned out.

 

[NES ST]

You can just gravity bleed it too

 

[RR13ST3]

Is there a bleeder or do you have to oil air out, ie vacuum pump ?

 

[Yo Ken]

Just finished up installing the new clutch line. As you can see from the pics you have to remove the air box. Once removed you will see the line. Pull the metal clips out and remove the line, its the same on both ends. It does get a little messy so be prepared to use some brake cleaner or just plain water. Water dissipates brake fluid very well. After I installed the new line I went to bleed it with the power bleeder and realized that it was not going to work. Pressurizing the brake reservoir will not cause the fluid to travel to the clutch line. I used my vacuum hand pump to draw the fluid out until there was no air in the line. It does not take much to remove the air from the line, about 10 pumps of the vacuum pump and it was bled.

On to the the road test. The pedal does feel different, but in a good way. It seems to be smoother when depressing and releasing the pedal. The pedal reacts much faster, but not as fast as a cable or the old z-bar style that came on older cars. You still know its a hydraulic operated clutch, but now its the way it should be. I don't know why it was engineered this way. Its by no means abrupt or aggressive. Gear changes are smooth as you want to make them. The only difference now is your in control. If you want mild shifts, no problem, if you choose to get aggressive, you now have a clutch that will react when you do. I banged a few gears without lifting of the gas and there was very little rpm flare, and no increased harshness to the drive train. Speed shifts are a delight with no lag whats so ever. A quick bleep of the throttle, pull the handle, and your in the next gear with very little to no rpm flare.

A quick side note. I'm not telling everyone that they need to do this modification to the clutch line. In my opinion restrictors are not needed for a performance car and feel clutch wear will increase when shifting hard with the stock line. Its not for everyone, but it makes it a much better drive for me.

 

[NES ST]

So you have it restricted or unrestricted ? It is not clear on your post
