So I Think My Old Pressure Plate Went Out Because of Rain

We’ve been getting alot of rain here in Colorado as of late and I think some water got into my master cylinder, worked its way into the slave cylinder and caused too much pressure to build up and subsequently caused the pressure plate to fail. Thats my hypotheses anyway. We are supposed to get even more rain in the coming weeks according to the local weather forecast and I wanna fashion something up on my clutch resivour. I could use some help working it out.

All hydraulic clutch systems have to be vented to atmosphere, Ford decided to put the vent hole on top of the resivoir cap on my Ranger;

Which means given enough rain, water may work its way into the system. I want to create a filter of sorts that will still allow air in and out of the system but will limit the amount of water that can get in or clutch fluid that can get out.

I was pondering the idea of wrapping some type of cloth around the resivour but that may actually make it easier for water to get in. Any other ideas?

Order some pizza, use the pizza table to fashion some sort of umbrella.

I know you don’t get much rain ordinarily in Colorado, but here in the UK we get quite a lot of rain and I’ve never heard of that being an issue. Perhaps a plastic cup upside down taped to the top with a hole in the side?

I know you’re probably kidding, but that may just work. Id probably fab something up, but you may be on to something there

Oh no, I was serious. The diameter should be close enough that you could just epoxy/sugru/rubber band/otherwise attach the legs to the cap in some sort of relatively permanent way.

You sure? Drain some of the fluid out and see what its consistency is, that’ll tell you if water got in. Though I highly doubt water got in there, unless the rubber boot in your cap was torn and you submerged the entire frontend in water.

How did your pressure plate go out? I’m not sure I’m following everything, if there was excess pressure in the line then the clutch would start to engage and you’d get clutch slippage, which would be very noticeable. Though part of the reason for the vent hole is so that when you aren’t pushing on the clutch the system is at atmospheric pressure, hence why I’m confused.

Im not saying its bad now, but when it did go out previously, we had monsoon levels of rain for days on end. So Im just making assumptions here and trying to find an inexpensive fix to prevent it from happening again (assuming Im right). Also since is been raining again, Ive noticed it getting stiffer, its not doing what it was, but its not as light as it was the day I brought it home anymore

Have you done a clutch replacement, and if so how long ago?

Ya, it was replaced under warranty after 7000 miles 500 miles ago. A few prongs on the pressure plate were bent

Did they do a disc / pressure plate / slave cylinder all at the same time?

They did everything but the master

Hmm, assuming none of the parts failed the only thing I can think of is a bit of air in the line, maybe check the slave to see if it’s weeping at the bleeder.

Best of luck, hope you find out what’s going on.

While you certainly don’t want water in your clutch or brake fluid, it’s not going to harm the clutch mechanism (of which the pressure plate is a part) itself, only the hydraulics, and even then, it will only do so over time, rather than rapidly and catastrophically.

The vent hole is a necessary part of the system, so you shouldn’t block it up, and it’s probably small enough that you shouldn’t have to worry about water getting in unless it’s pooling on top of the cap, but some kind of protection isn’t a bad idea. Maybe cut up a plastic bottle to sit on top of the reservoir?
