Re: Brake master cly replacement.
That is a spacer to hold the side brackets in alignment I believe. I will look at the pedal assemblies I have but mine are A1 and the A1 assembly is different from the A2.

Re: Brake master cly replacement.
Dan, not so sure that bracket you show is the same one. The bracket he is showing is in between the two side frames. Too bad the spider photobombed your shot.

Re: Brake master cly replacement.
Yep, that's the same bracket, that is the New A2 Tub that Ed had up at Brooksville, the end of the 2 brackets that hold the master cylinder and brake peddles bolt to it.

Re: Brake master cly replacement.
Isn't the one you are showing welded to the body? The one he is talking about is a small piece that goes in between the two MC supports and appears in the diagram to be in a different spot from the peddles.

Re: Brake master cly replacement.
I'm going to go with the "missing" bracket is ok to not have, if was even supposed to be there in the first place. Sounds like there are some slight variations of the backet design. The one that is attached to the dash is there.
The way my mind works is if something is in the manual or diagram, there's probably a purpose. That spacer part seems pretty benign to me, but wanted to check in case there was something important I was missing. Thanks guys.

Re: Brake master cly replacement.
I was going to bench bleed the master and read the documentation that came with it that said not to do that due to risk of bottoming out the piston. I would guess that if one is careful not to fully compress the piston, then it is OK?

Re: Brake master cly replacement.
If you're talking about #8 in the diagram, that 'spacer' does give the bolt that passes through it something to press against, otherwise the pressure there might deform the bracket enough to cause binding problems at the pedals. I'm not saying that's actually the circumstance, but the possibility for it is there.
I'll say this again, just in case no one was listening. It is far easier to remove the whole bracket in its entirety, do the work outside the vehicle and then rehang it and that process can be made much easier if you have a second person there to assist you....
...which is why you should be nice to people.
I'd venture a guess that the guys in Ordnance Maintenance kept a few of those master cylinder/pedal assemblies on the shelf, built and ready to install.
You can see a pretty good image of a completed and assembled unit here -

Putting that completed unit back up in there is a piece of cake.

Re: Brake master cly replacement.
So did you pull out all of your wiring to get it out?

Re: Brake master cly replacement.
No, I didn't have to remove a single wire beyond that of the brake light switch. Wiring was all above it as I recall. It was a very simple and straightforward job....except for that sneaky transverse bolt that I overlooked (#19 I think) but that oversight was on me. Once I figured out what I had forgotten it was a piece of cake.
I'm not claiming it was the kind of job that was an absolute joy to do but it IS the kind of job where it always pays to have someone to hand you tools and make sure you have everything you need as the work progresses. That's the best advice I can give no matter how one decides to do it.
