Clutch Hydraulics

[cookie]

So I changed my 99 Forester clutch slave, hose, and gaskets as reccomended in the TSB to the newest numbers.

The clutch was still inadaquate as it still would catch near the floor and clunk back when hot in heavy traffic.

I changed the master cyl and now it acts like it should.

This makes me wonder if I really needed to change the slave and hose, but frankly it makes me feel better.

The car has about 95,000 miles on it and since the updated clutch was installed at 89,000 the linkage has been getting progressively worse.

By the way the new clutch still feels fine.

I replaced both/all at the same time on my legacy... definate improvement. Curious about your experience though, not getting positive results until replacing the master. I assume you flushed/bleed/replaced the fluid when doing the slave and hose? I adjusted the connection at the pedal assembly to improve the engagement point... world of difference! Wondering if it would ever be benefitial to use a braided stainless clutch hose... or try the PDM slave that changes the action.

When I was a commercial mechanic I changed dozens of these on Ford C series. I used the same procedure.

When I pumped the clutch to bleed it I was just not getting an adaquate pressure from the master.

As long as I had to remove the master anyway I felt better to change it.

When you adjusted the push rod you may have caused the master to give a slightly better stroke.

When I was a kid with less money I would have just rebuilt the master.

I also noticed deposits in my master that looked like dirt accumulation. this may mean that no one changed the fluid in the past and caused the problem.

Still nearly 100,000 miles is not all that bad out of hydraulics.
