[Tigers] Tigers Digest, Vol 15, Issue 103

Sat Feb 19 15:37:49 MST 2022

 Now I am confused.  Take out circle clip , insert plunger, then washer, reinsert  circle clip, dust boot, return spring, 3/4 cup.  Place u end of plunger in brake pedal, insert Clovis pin, insert cotter.
Brakes are now engaged and locked up with no pedal being applied.
What is going on?  Ideas?
Thanks

Here is a YouTube that might help you understand the assembly.

The disc on the rod goes into the bore then the circlip fits into the bore holding everything in.

The hardest part is getting a new rubber boot on without splitting it which rarely happens.

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.

   Yup, it was assembled WRONG. 
   Yes, it appears to be assembled according to the photo that was posted from the 
   shop manual... which is wrong. 

   The circlip must retain the washer that is captive on the pushrod.  Pushrod should NOT 
   fall out loose from the master cylinder assembly. 

   Hopefully you did not sustain any injury or damage to your Tiger.

 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.
