Hi.

I'm new here. Intro and pics posted here - [deleted url]
Oops, can't post links yet. Please look in the "new-member-introduction-area" for my post.

Truck is new to me, again. Although my brother & I drove it back from VA a couple of months ago, with no real problem, a few days ago the clutch went out. Peddle goes to floor, with no resistance (only the return spring). Oddly enough, this happened on my back from getting it inspected for new plates. By the way, it passed!

Get it back in my driveway and see that clutch reservoir is low, very low. Tell my brother, he says, "Oh yeah, I forgot to tell you to check the the reservoir before every drive. Even if I don't drive it, it gets low." Thanks bro!

Looking at the master cylinder, it looks damp. Rusty and damp. Top it up with fresh fluid. Now I can pump the pedal a several times and get some clutch action, and engage the gears, but the pressure does no last. Next day, no pressure. And, the fluid is already very dark.

So, based on wetness, I'm thinking it at least needs a new grommet (?)between the reservoir and master cylinder, but I can't seem to find it online.

I don't want to mess with bleeding, until I get the leak fixed. If the leak can't be fixed with a new grommet, I guess I could replace (or rebuild) the whole master cylinder. Maybe the slave too.

I also notice a short piece of rubber hose, on the firewall, between the solid tubing of the clutch lines. Connections are rusty too (and perhaps damp). What's that piece of rubber line for? If I can get it part, I figure there are going to some o-rings. Are those available?

Well today's goal was to see if anyone knows where to buy that grommet, and if that incremental repair plan makes.

Thank you in advance.

Sincerely,

Eric W

I've owned a 1988 B-truck since back in 1994. I will tell you that the clutch hydraulic systems on these trucks seem to have issues. I've replaced the clutch master and clutch slave cylinders on my truck several times with new (don't waste your time on a rebuild kit), and maybe consider getting those with lifetime warranties. I ALWAYS flush out the entire system when I do that as well.


I've also replaced BOTH flexible clutch lines on my B2200, don't know if your B2600i truck has just one, so I suggest getting new there too.

Thank you for that info.

I am pretty sure my clutch line has only one flexible section (the one up on the firewall).

Trying to figure out if just the seal/grommet between Reservoir and Master Cylinder is available.

I think that would be a good place to start before tackling the other problems.

Warm regards,

Eric

Could be, I'm only familiar with B2200 models.

Search out to see if dealer part 030549686B fits your model and is available. I know that years ago I was able to get a rubber seal for the brake master cylinder at a dealer.
