easy way to test the booster. pump pedal till its hard, hold depressed, start engine, if it sinks about 3/4 of an inch or more, booster is working.
Bear95 and Bex like this.

And while this may not be helpful, from personal experience I find that a very hard brake pedal might indicate a hydraulic fluid blockage somewhere in the system.

LSPV blocked? or at least partially, will still allow brakes to operate, but at nowhere near full effectiveness

Just to update, I replaced both rear slaves cylinders and the flex brake hose at the rear axle and braking and braking feel is better. Rears will now go all the way to locked in a controllable manner. Both sides had sticking pistons at the leading shoe.

I attached a couple of pictures of my tracker - interior is just as clean and original as the exterior.

Thanks for all the input!

No, blockage in hydraulic pipe going to the rear brakes which prevented the rears from braking. While I was still able to brake with 80% effectiveness, the pedal was extremely hard.

You didn't even mention that it was a Tin Top. What did you find out about the vibration? Have you tried switching the tires front to rear to see if the vibration changes?

I did try that with no change. Ujoints were free with no play as well. I just got a bearing and seal kit for the txfr case and am looking for a shop to just pull the rear cover and replace the roller bearing the slip yoke rides in and the seal...

Bex,
Interesting that... I will have to look into that valve as well I guess.
Are replacements or rebuild kits available?

Are replacement LSPV or rebuild kits for the LSPV available anywhere? I could not find one anywhere on the interweb, and various forums had folks replacing them with manual adjust ones or just bypassing altogether. I don't know if I have a problem with this for certain but don't want to mess with it unless I have I have a replacement or plan for converting it...

What have others done?
Thanks!
Doug
