Hoping For Some Advice

[SandalsBoy]

CAR: 89 R32 GTR.

Problem:

The bell shaped metal housing that is attached to the firewall and to the piping for the clutch fluid reservoir has torn and all fluid clutch fluid leaked out. tear is pretty severe, much like a can being opened, inside i see a coil/spring of some description wrapped around a large metalic line or bar.

Obviously the clutch doesnt really disengage anymore and the pedal feel is far from normal, having very little resistance for the first half when depressed, then having a very firm spot which when depressed further causes a "ping" sound and the pedal to skip/drop a few centimeters before becoming firm again.

Questions:

1. Has a fluid leak caused the tear or has the tear caused the fluid leak? (fluid levels were fine 2 weeks ago when last checked)

2. How hard is it to get this fixed? Costs estimate?

3. What is function of the bell housing?

Any help would be much appreicated and apologies for the noobness of my descriptions. Thanks in advance.

Picture aint working for me, but it sounds like the clutch master cylinder which is an easy fix.

Two bolts fix it the to firewall, one bolt to back of clutch pedal in the pedal box (this ones fiddly), and one hydralic line to clutch slave cylinder - thats for an Rb30 anyhow. Bleeding the clutch afterwards will be the most fun part of the job.

Paid $40 for mine, will be a bit more for a skyline

Thanks for the reply mate. Sounds less serious than it looks. Can anyone who can see the picture verify that this is what has happened?

Yeah, that looks about right.

that's the clutch booster, not the clutch master cylinder that has broken - no idea how you've managed that (you might want to take a pic of the pedal and bracket inside the car too, it might have broken first.

its a bit of a pain to change but you should be able to pick one up second hand they are pretty reliable.

If you go to wreckers you might need to tell them its the clutch booster twice - I think its a bit unusual to have vacuum boost for the clutch, most cars only have it for the brakes. Might as well do the master cylinder at the same time they are pretty cheap.

Hrmm any theories about how this could happen? Wouldnt want to replace it then have it reoccur. Prefer to find the cause of the problem rather than just fix the symptoms.

Bare in mind that all the clutch fluid has leaked out also... not sure if makes a difference.

[Duncan]

well I was wondering what the pedal looks like, the clutch bracket itself can break which means you might have been pushing at a wierd angle = broken booster. But I've never seen this before.

Yah, for the front of it to get punched out like that, id thought the peddle wold have to over extend. Check the fulcrum point under the dash. Very strange.
