No clutch preasure \ action- HELP
#1

So after putting on some great miles this weekend with the car running strong, I had just stopped at a stop sign, clutch in 1st gear selected and bam stalled violently like I had let out the clutch fast with no gas. roll the car back to find a puddle of fluid on the drivers side of the car. pushed the car back to my house got it up in the garage but it's still to hot to work on. any guesses \ places to start? I have removed the under carriage cover so far and taken a peek just to see dripping fluid but nothing that jumps out at me. Thank you all in advance.

slave cylinder would be the first one i would look at - this puddle is the classic symptom



after that, the next likely candidate is the high pressure hose



the good news is that it's not going to cost you an arm and a leg



the bad news is that you should replace the master too



the problem is that a single new strong hydraulic component adds pressure to the other weak ones - you may well find that if you only do the one that failed, you will then blow another of the other ones

<img src="/forum/images/smilies/968/rolleyes.gif" class="smilie" alt="" /> It's the hose, I got under the car and had my GF depress the clutch pedal, and I saw it spray out. Thank you for the quick response. I love this forum!!!

Oh yea, the dreaded, and frequent hose failure. There was a rash of this going on a year ago. At 10 to 13 years old, all the original clutch hoses are on borrowed time.

Josh -



That is a downer after what was a great day of driving. A pain in the butt to be sure, but I'm glad it's just a hose.



Oh, and in case I didn't give proper recognition earlier today, thanks for putting on the tour and for the spare quart of Royal Purple - the first a day-maker, the second a life-saver. <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />



I hope we'll visit again soon.



Also, Dave, thanks for the heads up on the aging clutch hose. I doubt mine has ever been replaced by any PO. And with over 178K miles, I will have my shop check out the condition and replace on my next visit.



Best,

Just went through the identical experience. Replacing the master cylinder is such a pain I had the shop do it. The clutch, which was new 12k ago, has never felt better. I did not realize the impact the slowly degrading hose and cylinders was having on clutch operation.

As a precaution, I had my rubber clutch hose retrofitted with stainless steel braid at a local hydraulic shop. Onlly $30 or $40 if I remember. They take your old hose, save the, metal bits and braze on fittings that accept a -3 braid. Will last forever. Look in the yellow pages for a hydraulic hose repair shop in your area. As far as I know, there are not aftermarket replacemements in steel braid.

Sounds like this is what I'll do. So will they be able to use my bad hose and "add in" the new section?



Thanks,



Josh

Yes, they discard the rubber part and save the fittings.

I already found a shop in Sacramento and I'll be dropping it off at 7am tomorrow morning. So not only is this cheaper than buying the new hose it's better. Are there any other hoses that could benefit from this treatment? Besides the obvious being brake lines.



Thanks for the tip <img src="/forum/images/smilies/968/biggrin.gif" class="smilie" alt="" />

When the guy tried to source the fittings to make hose assemblies from scratch, he came up with zip. The 12mm female inverted flare was the tough one. Haven't pursued it any further. Suffice to say there is any number of hydraulic shops that can do this if you are willing to put the car down for a day.

The thing with brake lines is, if you want to go by the book, they have to meet DOT specifications. There are aftermarket sets out there for $100. Not worth the trouble of having existing lines converted for that money.

Dave - Perhaps this partially explains my mushy clutch?



Josh - What is the shop in Sac you are using? Perhaps I will do the same <img src="/forum/images/smilies/968/smile.gif" class="smilie" alt="" />

Quite possible. If the hose is about to go, it will be ballooning first. More often than not, a soggy clutch is due to it needing a good power bleeding.

I'll be the first to admit may mechanical talent is zilch. <img src="/forum/images/smilies/968/sad.gif" class="smilie" alt="" /> I can change my oil and filter and that's about where it ends. I have an appointment with my mechanic next week and will have it checked out then. Unfortunately, I have made significant contributions to his child's (yet unborn) Harvard annuity fund. <img src="/forum/images/smilies/968/wink.gif" class="smilie" alt="" />



Thanks for the tip, Dave. BTW, I love the LED taillight - all "bulbs" good and still burning bright!
