I'm having a weird intermittent problem with my clutch. Only happens on startup for the first time of the day and only sometime (2-3 time a month). It will go straight to the floor and I'll have to pump it a bunch until it builds up pressure again. Then it will function like normal until the next time it happens. I'm thinking it may just need to be bled but not sure. Tried bleeding the slave cylinder a couple times the conventional way but hasn't gotten rid of the problem.

Any ideas?

bleeding wont help with those symptoms. Most likely your clutch master is leaking internally, and possibly leaking into the cabin. I usually replace both master cyl and slave when this happens, had it happen on a few cars, always random times and might not happen for weeks.. You can pull the carpet back under the drivers side and check for fluid inside to confirm its the master.

I have had to replace slaves on all my audis. BUT, one thing that happens is that air gets into the system through the top of the blue silicon, cloth-covered feed hose that goes down from the side of the brake fluid reservoir to the top of the master cylinder.

The end of that hose can start to dissolve and let air in. You can just cut the crappy part off the end, but there isn't much extra. Pain in the bootay to replace but should be done with the master and slave at the same time. Cheap insurance, trust me :p

Wouldn't my brakes be affected if it was the master cylinder?

Oh and I should mention that I don't have to add any brake fluid either...

I do however have a very very slow Pentosin Power steering leak somewhere. I have to top the fluid off maybe 2 times a year?

I think someone may have already replaced that as I'm not seeing a hose that is cloth covered hose.

Edit... I'm a dumbass.

The brake MC and clutch MC are different things. Clutch MC is located in the driver's footwell directly behind the clutch pedal. Nothing is pressurized until beyond this point...the clutch MC is gravity-fed by a line from the side of the brake fluid reservoir.

Ah. I just assumed they were the same as normally in other cars there is a separate reservoir for the clutch MC. But still wouldn't I be losing brake fluid if the clutch MC was leaking?

Yeah. Just saw that after posting that it's not much more on autohaus . The master is beck arnley part number 072-8130. Do you think that'll work?

Yes but there's a chance that you'll get sent the wrong one since there are two versions of the slave. One has an adapter fitting for fitment on a4's hence why I said to get the one from pelican for a boxster because I know it's the correct one. The oem is boge/sachs

So Austin.... the Beck Arnley master cylinder is FTE brand. Is it just R&R or is it like the slave where there may be problems. Just wonder as I can get the Beck Arnley one for under $30 here new.
