R33 Clutch Fork Boot?

[defari]

unsure if its the standard clutch or aftermarket clutch in my 33 (hasn't been changed since i bought it, previous owner wasn't sure either)

i've noticed lately that now i have to push the clutch all the way into the firewall otherwise it crunches, I used to only have to press the clutch 3/4 of the way to the firewall... my mate says its the clutch fork boot. would he be right?

If it helps, i noticed today sitting at the lights, on a slight incline.. clutch in, in first gear, take my foot off the brakes, (clutch still fully in) the car rolls back the slightest bit but as soon as i give a little gas the car stops moving backwards even tho the clutch is still fully depressed.. If i dont blip the gas the car keeps rolling backwards.

Any ideas?

Also, i dont have the cash just yet to fix it, is there much harm that can be done if i drive it for another week or so?

it wont be the boot at all

either a pivot issue(often break), or clutch failure(pressure plate issue) of some sort, or bad adjustment caused by master of slave failure

maybe try bleeding the fluid for starters, first at the nipple on the master, then if still shit, bleed at the slave

mates having a little bit of the same problems as yours, we will be replacing the slave as thats what we think is causing the problom, his is on holidays so will let you know when he gets back if its the problem or not.

let me get this straight, while the clutch is fully pressed, and u press the accelerator, the car stops rolling back, even if you have had the clutch all the way in the whole time?

as lotsalag said, won't be a boot issue. the boot is simply a rubber seal. i'd say it will either be an adjustment issue or a pivot bolt issue. i've seen a few skylines snap the pivot bolt (mine included).

there is a small chance the that actual clutch fork is bent, but i doubt it unless you have a super heavy clutch.

Air in the system, worn master/slave cylinder, pivot ball snapped/worn, or pressure plate worn.

If you can get under the car, pull off the clutch release arm boot and have a look inside with a torch. Get a mate to sit in the car pushing the clutch pedal in and out. Will give you a good idea what is happening with it.

yep.. so its like the clutch is grabbing the slightest bit (hence the car stops rolling back) so even with the clutch fully in, its still grabbing the slightest bit..

i dont get any clutch smell, gears dont crunch. The clutch feels quite heavy (same as my old car with a hd clutch in it)

will bleed the master/slave over the weekend.

What was the solution to this? i have the same problem

With the clutch pedal all the way in, i can either not get it into gear at all or if it does happen to (on occasion as it is temperamental), i roll forwards lol, while the pedal is still in.

Did this once and since had got the lines bled etc, has had new push rod and adjustment done and was all sweet for a while now its back to this again. ??

[Luke Vincent]
