Matilda's jammed rear drum brakes

Question Folks....

I pulled by brake master cylinder off today as it was leaking brake fluid - I'm not exactly sure, but I think the seals (which were all replaced recently) had been forced off, or at least had fluid forced past them, as a result of my brake jam issue.

The seals are all intact - except for a small perforation in the external ribbed boot that goes over the end of the master cylinder. I take it this boot is more a "keep dust and crud out jobby", rather than being a fluid seal, so would I be correct to think a minuscule perforation in this boot would still be serviceable?

Yes. In fact, sometimes these have a deliberate vent hole. Pack the inside with rubber grease.

Well........
Not overly impressed as FBJ brand was all they had.

Well - Killer and I went around to Dave's this arvo to try to get this all sorted - but all we achieved was a build of Dave's press and to discover that one of my new rear wheel cylinders is already buggered. Actually, we also achieved a move of 3 Series engines, so at least Dave is happy.

Anyhow - we then discovered that Dave's press was too small to do the job. So we tried the old drop method - of course, this didn't work either....

So we then tried heating the collar before doing the drop method again - still no go....

So final resort - Dave is taking axles to Amberley tomorrow to see if he can use the press there.

Alas, Matilda is destined to remain a garden ornament for some time longer, it seems. I must have Australia's most expensive non operational Series vehicle :mad: (And add to this - I can't work out how my bonnet spare wheel carrier works - plus, my Puma is going back again for more warranty work - what have I become? :( )

Jynxed,

I found the gas bottle for the propane torch... Its empty.

Assuming I get the axles sorted tomorrow do you want me to come round, drop them off and sort the spare wheel carrier?

If it's OK for you - dropping the half axles off would be grand - but I've sorted the spare wheel carrier! :D (Thanks to the great Series 1 online help!)

Dan, you forgot to include the shot of me lifting the 2.25 motor above my head.:D

Cheers, Mick.

Basically no joy from the RAAF base.

any press that was big enough to let me get the backing plate through safely had support plates that were to wide to fit between the backing plate and the flange.

I bodged a set of plates from the scrap bin but they gave out at about 8T of pressure, I could have pressed harder but didnt want to bend or break anything on the shafts.

went to 400 Degrees on the collar to have another go but got nowhere.

I stopped there, the axles not being mine, I didnt want to delve into the "unfriendly mechanics" book of tricks.

Thanks for trying though, Dave. I appreciate you did what you could for me. :)

So - I'm back to square 1. Reckon I have Australia's most expensive, completely non operational, garden ornament Series vehicle. Old mate from Gympie certainly saw me coming. :mad: On top of this, Warren T Ford has also just been taken back to the dealer - what a heap of junk that thing is. One's clapped out - the other crapped out.

Hopefully someone is SE Qld has a press that can separate my blasted backing plates from the axles - new axles are $1700.00 :eek:. If this issue can't be resolved without that expense, I'm going to have to shelve the old girl, I'm afraid. :(

Have you tried grinding through the retaining collar and then pressing? This worked for me and only took about 10 tons to work.

I have heard of people getting the collar turned off in a lathe, which has the advantage of needing no pressing at all.

Don't give up yet, someone else near you will be able to help,

Cheers Charlie
