Tampa 928s

The top bolt is stripped what size should I go to with a tap or use a Sae bolt?

The other issue, I hooked the brake bleeder to the M/C to bleed the slave set at 12 Lbs, started to bleed but fluid started pouring down the motor from the M/C. By the time I got the car up in the air the bottle was empty. It seems like the plastic reservoir is moving and leaking around that seal. The brakes are hard but the clutch is still not pressurized.
Dam!

Old rubber in a hot engine bay, the bane of all 928's.

Good luck.

I would recommend taking that cover off and helicoiling the hole with the right size M8x1.25 iirc.

if the plastic resevior is leaking fluid from the seals going into the MC then you need to remove it and replace those seals immediately.

and do a search on how to bleed the clutch circuit but you will have to have a good pair of c clip pliers, and like to be under the dash

The master Cylinder fluid is the same for both the brakes and slave correct!
Is there a rebuild for the fluid plactic section seems like its the rubber seal; with out removing the whole unit? As you know my next ? is what do i need to do to repair this?

Hey Tampa,

Hang in there man. Sounds like you need a brake . Sorry I couldn't resist.

The brake fluid is the same for the clutch slave, all connected through the same system, through the same reservoir.

Not sure what's available for the brake master cylinder short of replacing.

Take your time and break it up into smaller jobs, check them off as you finish them, walk away, then come back fresh. Sometimes pushing too hard can cause more problems than you started with. Don't think of it as one big job, it will make it easier to cope, dude.

Lizard928

if you get a MC rebuild kit it will come with the two round rubber seals needed to stop the leaking,

and yes the resevior is the same for the brakes, and the clutch. you will be able to pop the resevior off and replace the seals without removing the brake MC

Hey Mark, do you have a set of work shop manuals yet?

BTW, sorry about not making it to the Corvette show the other morning. My night of partying didn't stop until 6:30 am Sat. so I was in no shape to go anywhere.

The request to take a brake was well thought out.
I did take a time out and found that my Bleeder kit did not contain a gasket on the cap and it was leaking from the top seemed like the seal on the master
That said I will try to pick up a seal tomorrow; the fluid was full so no leakage as far as I can see. But the bleeding of the slave as far as the posts I could find is as follows:
Try again using a gasket
Pump up To 25 Psi bleed push pedal to flood bleed and do several more times.
Connect the caliper to slave and pump; flows fluid backwards and will burp it.
Remove slave push rod till it burps
Quit and sell the car "Just kidding"
The belt is on and I'm waiting for my Compressor rebuild kit to fire it up!
Then the motor mounts, the only thing I see its a lot easier to get at the mounts with the air off. But I really want to crank it up first. Oh yea and the bolt issue. Let's not forget the shocks!

Mark.........good you found the leak issue; hopefully all's better tomorrow with a new gasket.

BTW, 25psi is probably too much pressure............I use 10psi with my power bleeder when doing the brakes.

leperboy

I agree, at 25 you have a chance of blowing out a seal or connector. The WSM recommends 14PSI for bleeding the clutch slave, so go with that first.

Matt

Mrmerlin

Hi I would recommend that you go no higher than 14 psi to pressurise the brake/clutch resivour you will wind up blowing off the resivour from the master cylinder or the clutch feed line to the clutch master. BTDT..........Stan

Mark, I did this exact same job two weeks ago and I had success w/ 8 psi. This is a case where more is not better.

leperboy

Fabio, did you use the Motive power bleeder with a 45mm adapter, or what type did you use?

Thanks, Matt

Fabio421

Yes, the motive bleeder w/ the Euro adapter. It worked flawlessly. I had a heck of a time trying to get the slave bled after replacing the flex hose in the clutch circuit. I finaly decided to buy the Motive Power Bleeder and I was amazed at how easy it was to bleed. I am now a believer.

Tampa 928s

Got a gasket from Ace hardware used for plumbing application it allowed the bleeder to work! Now I need to find a crows foot 17 and 22 MM or a short wrench or remove my hood to get the back connectors off of the expansion valve!
