71 clutch mc kit advice

[aussie2002]

Hi all - can a clutch master cylinder repair kit be installed (RHD car) without taking out the master cylinder - i.e from the inside of the car foot well?

 

Hoping its an easier job than complete removal.

 

Cheers

I have never tried this but now I have the strangest urge to go out and bust some knuckles in the attempt!

 

I'll bet someone here has some more sage advice.

I have no experience with RHD cars, but do have experience fiddling with my clutch master cylinder.  I bought a new one to replace the leaky one that came in my car and it started leaking within a couple of years; so I pulled it apart and tried different combinations of rubber bits to try to make it stop.  I learned that there are at least two styles of plunger assemblies and the rubber parts are different between them.  In the end, I was given another new master cylinder as a thank you gift and I installed it.  I never did get the first replacement to stop leaking.

 

The guts come out through the end that fits into the pedal box, obviously.  So you could conceivably remove the circlip and pull it all apart with it still installed in the pedal box, but it does not sound pleasant. 

 

Is it hard to remove a RHD master from the pedal box?

 

I will try to dig up photos that compare the different plunger styles.

Do you have your rebuild kit already?

 

Are RHD masters more expensive than LHD masters ($60)?

I have not found mine yet, but a search brought up this thread with some nice photo comparisons of the two styles

Thanks for your reply

 

Yes the RHD drive master is tricky to remove - but can be done - I have all new lines, engine bay paint, cables etc in that area and it will make a mess.

 

I haven't got a rebuild kit, but Jaymic have one for about $50. A new RHD master is around $300.

 

I don't have carpet or any interior in the car yet, so a little bit of fluid drain inside isnt an issue.

OUCH.  I can see why repairing it would be preferable.  I found the post in which I shared some of my personal experiences.  I felt a little silly rereading it, but will share it anyway.

I think the pedal might get in the way of pulling it apart in situ. This is one of those jobs that you really can only do justice by taking it apart. 

 

You really need to inspect the bore to check whether you have any corrosion that will comprise the seals. This may be honed out or even, in the worst case ($300 replacement case) you might find getting it sleeved with a stainless steel sleeve may be a better solution. There’s a few local companies in Australia that specialise in resleeving cylinders and it looks very competitive compared to, say, Jaymic’s cost for a refurb or new RHD master cylinder (brake or clutch). 

 

Cleaning up and managing old fluid when removing the cylinder is small beer compared to trying to work on your back, peering up under the dash trying to fix it in situ (if it is even possible with the pedal in the way).

Totally agree, however, if one must work up under the dash, the first thing to do is remove the front seat? It's the only way I can "comfortably" get up under there.

This thread makes me glad that I kept the old clutch master when I last swapped mine. Definitely didn’t cost $300 but then it was a few years ago. I have a pair of old brake calipers too and rear brake cylinders (which may not be worth repairing). I might order some seal kits and get them all preemptively repaired.

 

Wish I had a spare RHD master cylinder, now that is expensive and I note that even Jaymic seem to have stopped  offering them new now.

Thanks everybody. I’ve learned a lot. I’ll fully remove the Mc. Resleve. No shortcuts for me.
