M35A2W/W Master cylinder replacement

[wiggall]

Do I have to take apart the clutch , brake pedal assembly to replace the Master cylinder? I have removed the brake ltne. and all the bolts holding the master cylinder in place. But I do not have the room to drop it out.

Wiggall there are TMs on this site free to use by all of us I would suggest you give them a look it will cover everything you are asking!

If I remember right, it will come out but it is super tight. The rod and boot have to be off. I believe I had to remove the PTO shifter.

Mine would not drop and I had to remove a couple of bolts from sides of the master so it would slide into the rearward hole to get it loose. Instructions are in the TM and are solid but I didn't see any part about the bolts on the side in the TM but with those off it came right out. Read here:

Master Cylinder Replacement

As I dug into the rear axle and replaced the wheel cylinder, I knew I'd need to bleed the system and did a thorough inspection of the master cylinder and airpack. They appear to have been both replaced at some point but there was a small amount of leakage from the master cylinder around the...

I have the TM's on disk, and I do use them!

You OBVIOUSLY aren't holding your tongue correctly or not using the right swear words! It wiggles out without removing anything but the mounting bolts and lines. If you wait a week to put the replacement in you won't remember how to get it back in!

The appropriate swear words scare the offending parts into submission. Anointing them with knuckle blood helps.

I had some serious problems removing a MC on one of my trucks - mainly because there were two capped ports on the back of the MC that would not fit through the hole in the crossmember. Had to remove one of them so the MC would clear. I do not have any other MC's like that one, but I suspect it was for the dual brake setup on the later trucks.

I might have mis forgotten. The front fitting needs removal. All the rest, swear words, tongue and length of time between removal and instllation still apply!

Maybe mis remebered...it has been a year since I did one!

Sometimes a "blood sacrifice" is required !

If you don’t cuss at it, it won’t think you’re serious and won’t cooperate….

If you ain't bleeding, you ain't doing it right!

Changing the master cylinder is one of the more miserable jobs, depending. There is one fastener that is in a very tight spot and, if the master has been worked on before, is likely to have been "omitted" upon reassembly. I was very pleased to find that my master was held in place by accessible fasteners only. It works fine without that frustration inducing fastener. I left mine that way as well.

Take extra care to not cross-thread the brake line fittings.

YES !!! Don't cross-thread the fittings !!!! You think things are messy now, try finding and fixing a cross-threaded fitting !

That one can be done 'easily' if you use a deep socket, a six inch extension, a universal joint, another six inch extension and a ratchet wrench, with most of the assembled tool threaded through the hole in the frame crossmember. I have always put all four fasteners in. YMMV.

Must have worked! I am not Fluent In ARMY TALK, But I am very good in SAILOR TALK! I got it out today, will try Thursday to get the new one in!

Installation is reverse of removal!

Get the other three fastening bolts in and snug before trying that last one on the bottom outer side. That way if your vocabulary fails you, there is still the over-enginnering safety factor that will allow driving the truck in a normal fashion.

I guess I will have to you my Sailor talk backwards!
