clutch master?

I noticed my brake fluid was low the other day, and then found that brake fluid was indeed inside my footwell. I guess its time for a new clutch master. Hows the difficulty of this job?

You're right to change both. The hardest bolt to get to is on the master, but is dueable with an open and closed end wrench. Recommend a mityvac hand vacuum pump to bleed the air out after install.

Ok, new clutch master and slave are arriving tommorow. When i go to bleed the system, should i bleed the slave first, or the master first?

As noted the nuts that hold the master to the firewall are the hardest to get to. The easiest tool to get to them with is a 1/4" drive socket with an extension and U-Joint. One of them is hard to get at. But 3/8" drive will also work.

You don't really bleed the master itself. You bleed from the clutch slave. The slave can be a real problem if you don't know the tricks. The problem is the bleed nipple is not located at the top so it is very hard to get the air out once you have it in the system. I find it is easiest to use the power bleeder and bleed the line with the slave detached and held bleed nipple end up. Watch so you don't push the rod out of the slave. Once the air is out then bolt the new slave back onto the bellhousing.

Edit: One other thing. Stuff a rag over the flywheel inspection hole on the bellhousing where the speed and reference sensors are. You drop a nut or something down inside there and you may have to pull the bellhousing, which is basically a 20 hour clutch job, if you can't get the item to pop out of the starter hole.

your car has an assist spring on the clutch pedal so you will have to manually pull the pedal up until you get the air out. i used a power bleeder on mine but before it would work i had to pump the pedal a few times then break the line loose where it turns down behind the engine. also if you have your car on jackstands go ahead and lift the back of the car too so the car is level, if you just raise the front you won't get fluid down to the clutch m/c.

Hey everyone,

Thanks for all of your help... I went with the clarks-garage write up on the process. I bled the system with the help of a friend and had no issues whatsoever. The job took me about 3 hours with the occasional dropping of a bolt here and a nut there.
