clutch slave/master

mlang88 · 12-08-2009, 03:10 PM

well when it rains it pours. got in the 944 this morning to go to work and the clutch pedal only returns half way for the first mile of my drive. has anyone had any luck with the rebuild kits for both the master and slave cylinder? or is it a waist of money?

Thanks
Matt

Ya those are a PITA they usualy don't give you no warning.I'll say from experience "waste of money" are you doing both at the same time?

yeah im going to both, I had to drive into work I wounder how long it will hold up

do the high pressure hose too if it is more than 5 years old

I would recommend doing both - The slave is super easy but the master is a pain (on the Turbo anyway) but hear that it's easier on the NA.. Buy or borrow a bleeder before you start the job so that you can finish the job.

Pelican has a VG price with the free ship. Get the clutch MC. I did get the new slave cyl but when I took mine apart, I could have gone with the $20 slave rebuild. My bore was clean and no pitting.

The hose is a good part to change but double check the part for your car. I did not replace the hose on my '87.

Another maintenance item to order as long as you are working with the Brake MC
reservoir---new MC reservoir grommets (2). Just be careful when you pry the reservoir off-do not crack the reservoir. Install is easy. Put grommet in MC and lube reservoir fittings--press into grommets.

I have a spare master if you need one, it's porsche OEM.

The master isnt that bad. tight working space. Bleeding the system was the B!^*#. and climing under the steering wheel wasnt fun either. Took about 4 hours. I bought my thru Performance Products/ **********.com they had a good deal going at the time.

You'll need to remove the starter underneath to get to the slave to remove it. Definitely do both. You can probably get away with rebuilding the slave if it's not rusted, which is easy, and inexpensive. Either route you go, make sure to do them both.

with hydraulics, the pressure will find the weak link - rubber parts in the system have a life expectancy of 8 years maximum under perfect conditions - this means relatively consistent temperatures and humidity and flushing the system every 2 years - they fail from the inside, so you cannot see anything from visual inspection - if your parts are older than that, or you have not met the other criteria, you are on borrowed time with any component you do not change, and it will become the weak link and very likely fail shortly after you change the other components

do all 3 parts

and if the reservoir is shared with the brakes, like on the 968, flush your brakes while you are at it

Oh god dude. You don't even know the half of it.... I bought a 944 that appeared "just fine" and "might need a few things". You don't even wanna see the list of stuff i've replaced since i've owned this car. And that's only since..... april.....

Think of it this way. You're an awesome 944. You roll off the showroom. Your first owner buys you, and eventually gets a 911. He sells you to some guy who takes okay care of you. He gets something else and hands you off to someone who thinks the 944 is a cool car, but finds out they're expensive, gets rid of it soon as he can. That person does a bunch of cheap fixes, realizes it costs money to keep up on it, makes it LOOK great, and then sells it to the next guy. Eventually, the car becomes somewhat as a legend among people who have never driven them, and start calling them a "Poor man's porsche" and 85% of them get neglected and abused with no respect. People start buying them for their teenage kids. If by this time your valves haven't busted from one of the owners forgetting to do your timing belt and leaving you to rot because you're too expensive to do a valve job on, you're one of the lucky few! and not a parts car! The cars get insanely neglected and eventually rescued by someone who really DOES like them and care for them. At this point, things just start randomly broken since they've been neglected for about 90% of it's life. They start appearing to be a "PITA" when in fact, they've simply suffered the long breaking chain of events that take their toll on the unsuspecting victim known as the new owner.

Largest question is since these cars ARE so neglected in a vast majority of the time (sad but true, especially around here in my area) it's insanely hard to buy one without for sure putting effort forth on putting it back in "as intended" shape.

I say this as I'm sorta chuckling at my list of things i've done, and the fact that i'm so insanely addicted to them that I own a 924 AND a 944.... perhaps i'm a sucker for weird punishment!

Did you adjust the clutch petal to have 2 or 3mm of free play? I adjust it before I drive. You will not get an accurate "feel" if you try to adjust the petal after a drive.

My method is to loosen the clutch MC rod 13mm nut under the dash, and wiggle the rod (8mm)until I can feel it just touching the clutch MC piston. The piston has to be fully extended to allow for the brake/clutch fluid to properly enter and exit.

Has any one ever come up with quick fasteners for instant seat removal? It is so much easier to work under the dash without the drivers seat in place -

mlang88 · 12-11-2009, 09:01 AM

yeah getting under the dash when you 6' and +250lb is a PITA. yeah the clutch petal to has 2 or 3mm of play. took it to work this morning and it went in to gear really smooth it's usually tough to get it in to 2nd till it warms up the gear oil in the trans but this morning she went right in.
what oil is every one running in the trans?
now I still need a fuel damper. also I tried to adjust the afm with the o2 sensor but couldn't get a good reading it was all over the place on the volt meter jumpin frm 68,54,19, 9 just all over the place. do you thing that because the damper is bad?
