I recently had my clutch master replaced on my '77 Celica, and it's not able to keep its pressure anymore.
I'll depress the clutch pedal completely, and shift my car into gear, and while the pedal is still to the floor, the clutch slowly engages.

My mechanic had to essentially custom-fit a "compatible" part, and mentioned having to drill completely through the screw holes where the cylinder was mounted so that it would fit. I'm not sure if this could have caused this problem. It worked just fine for a good 2-3 weeks, so it gradually failed.
It's in the shop now (different mechanic) and he bled the clutch line entirely, so it wasn't a problem with air in the system.

Has anyone had to replace the clutch master in their Celica, and if you have, can you give me a specific brand and part number so I can order the part myself? If it took some tweaking to the way it's mounted, or required any other new parts, can you tell me how you did it?

I had a problem with my Corolla where I had to replace the clutch master 3 times before a got a good reman'd one. They'd all work for a week or two and then you had to pump the pedal to get it into gear.

You could always upgrade to a Wilwood clutch master cylinder.

Pretty similar to the stock clutch master. Only problem is you have to bore out the holes in your fire wall and clutch pedal bracket. I ended up breaking the one on the clutch pedal so I just made a new one.

Update:

My mechanic thinks it's the slave cylinder, and he has parts on the way to test it out.
If it ends up being the clutch master, then I'm definitely willing to upgrade to that Wilwood one.
What's the specific model number of that Wilwood?

3/4" bore size

part # 260-1304

*you have to change the male fitting for the hardline leading to the clutch master with a 3/8-24 fitting.
