Is My Clutch Goooooone!

I've got a Jim Berry clutch (not full monty) in my 32, and it has been behaving a bit weird.

The bite has moved very high up the pedal and is now very narrow.

As well as this it has started slipping a bit, but usually when cold.

Once warmed up, it doesn't miss a beat, but the bite is still high up and veryy narrow.

Because it wasn't like this when first installed, is it gone?

Could it be something else causing the change, eg need to bleed lines, master or slave gone?

any ideas?

Could be a couple of things. First place to check is the hydraulics...have a look under your car while someone pumps the clutch pedal, check to see if the release arm has full travel. If not, then it is an hydraulic problem, such as air in the system (needs a bleed), a leaking slave/master cylinder, or an issue with the pedal assembly itself in the driver footwell.

If the arm has full travel, then sorry to say, the gearbox will be coming out...and it will most likely be a worn clutch - the slipping is indicative of a worn contact plate - interesting that it gets better as it warms up though - could be a worn pressure plate, though this usually causes clutch drag.

Another possibility is the pivot ball inside the bellhousing...this might be worn or snapped off...but that usually results in clutch dragging symptoms rather than a high take up point.

      Nope, still smaller rear, put on the 4inch exhaust and picked up power everywhere, ended up just shy of 800rwhp.   Didn't seem to be hitting any walls either, so perhaps could have pushed for more but all maybes and the fish that got away etc etc.

      This could be sold and shipped to the US for many gold pieces. RMS has no say in that. Ask various Western Sydney inhabitants how it works.

      Ha ha ha, mine loves to spend, all on the dogs (they're our kids, and her spending would likely rival that of some people raising children!) the only benefit is, her spending is tax deductible as she runs a business in the dog industry 😛 The above all means she can spend race car budget quicker than I can. 😛 That and a lot of the things I want are very expensive, and I can be a bit "you want how much for that?!" And at other times overly impulsive. Or I start the w days of research, get to day 1.5 and get really annoyed that no one will advertise actual specifics and it's just marketting BS and I go "well, now I don't want anything to do with that now!" Also I hate paying lots of money for something I can make from $50 in materials. Then I get the shits halfway through making things and wonder why others who just buy parts have more fun... 😛

      Their 240Z with the RB26 would be a real nice thing to have in a garage to come out for an occasional weekend cruise It's such a cool thing in so many ways Sadly, we have a blue 240Z shell that I walk past every day, just sitting outside a shed at work, it has been slowly disintegrating and falling apart into the ground for the last few years, the owner cannot be found, and I am unable to "claim it" I've been told by work and the RMS, the rust in the body is excessive though, and it has had most of the salvageable stuff, like panels, trim and switch gear stripped off it over the last year or two, work keeps threatening to put it in one of our metal scrap bins, I wish they did though, as it makes Mark sad walking past it
