I meant the check valve in the vacuum line from the brake booster to the intake manifold may be leaking when it gets hot, causing the power assist to not work (which means you have to push harder on the pedal, though I don't think it goes soft).

Do you know the size of the bleeder valve for the clutch slave cylinder?

 

If you have/get a Power Bleeder, you don't really need it. We tried one for the FD and we couldn't get it to stop leaking. So, I'm only using Speedbleeders on the brakes.

 

Did you know there's a steel ball bearing inside the bleeder hole?

 

Wellw hatever it the problem is when I fix it up I will post it. And no I doubt it is the brake booster. No leaks and it doesn tget harder to push it just feel sliek theres air again after driving a bit.

 

What? There's a stainless steel ball in a speedbleeder?



Thanks for the info but I'm already aware of how they work. However, the size that is suggested for the FD on the clutch wouldn't stop leaking. It's possible they sent 2 of the wrong size, but I doubt it.

If you have a Power Bleeder, you don't need really Speedbleeders. The reason is that once you pressurize the brake/clutch system, you don't need to pump the pedals. All you do is open the bleeder and then close it when you have a decent stream of liquid (not air). Thus, no real need for Speedbleeders (unless you just want to have them).

 

There was no need for the condescending remark. Maybe you missunderstood what I was saying but I think I clearly stated bleeder hole not bleeder valve or bleeder screw... there is a difference in this case. When I removed my clutch slave cylinder bleeder screw,I noticed the end of the bleeder screw was different. So I looked in the repair manual (H-15) and noticed a steel ball bearing in the bleeder hole. Now I'm not certain, but I think if you attempted to install a speedbleeder valve in the bleeder hole before removing the steel ball bearing from the bleeder hole, then you might not obtain a seal. Sounds logical to me but weirder things can happen.

 

To whomever may know the answer to my question...
EDIT: It's the same size as the front calipers (thread pitch only)

 

I tried all sorts of things and it ended up not being worth the effort to continue. This was many years ago so I can't go into detail as to everything we tried to get it to work. The Power Bleeder solves the problem in a much better fashion. If you lose pressure in the braking/clutch system, even with Speedbleeders you have to do some serious bleeding to get it back. With a Power Bleeder, it's a 10 minute or less job to bleed the clutch and the brakes without the need for Speedbleeders.

 

Could really worn down pads cause a spongey feeling?
