[Tigers] Tigers Digest, Vol 15, Issue 89

It seems to me that assembly is pretty straight forward. The pieces are all there. The internal piston part is ok. Then the pedal’s attached plunger with the washer in place is pushed into the cylinder, including the washer. Yes the washer has to go inside the cylinder.  It has to fit the bore of the cylinder. When that is in past the circlip groove the circlip is installed and that keeps the whole mess in place. The  external boot is snapped into place over the end of the master cylinder to keep the leaky stuff inside.  And the dirt stuff outside.  Tain’t rocket science here, folk.  It was incorrectly assembled before. If that one? Then check the clutch master as well  because it may have been done the same way.

That totally matches what I would expect to see.  That round disc should have been on the inside of the clip.  So either it was not assembled that way, which is odd.  Or perhaps the disk is a smaller OD than the ID of the MC and the clip.

Hello all.

I pulled apart the brake actuator today and the whole thing just fell out of the rubber boot?  Rubber boot was split.  There is a circle clip up next to the master cylinder plunger still in place.

Here is a picture of my brake setup which does not match the picture below from the workshop manual.

My question:  How is the brake actuating rod retained in the master cylinder so it will not come out?

There are so many oddities here.  First, at one end, the plunger should  have a disc at the end, with a circlip that holds it in.  That rubber boot would likely hold in the disc, even if the circlip broke.  So since it “came out” of the rubber, it sounds like the center of the disc is some how flawed.  But FWIW, I can’t imagine how that would happen unless something was quite odd in the assembly.

I had a little scare the other day backing out of the DMV parking lot.  No Brakes.  Discovered that the brake plunger had come out of the rubber sleeve going into the master cylinder.

The only thing that could have happened is when I got out, my foot pulled the pedal back towards the interior and this pulled the plunger out.

It only had the spring, plunger and rubber plug to hold the plunger into the master cylinder.

Is there suppose to be something else to hold the plunger in place?

Thanks

Joel,

Your master cylinder was apparently assembled without the circlip.  See #2 in the attached from the workshop manual.
