Outstanding questions:
- Is it possible to remove the handle (where your fingers go) without destroying it? I'd like to paint this thing while it is disassembled.
- Is there a spring that I am missing and not shown in the parts catalog? I saw a reference to this in a thread but have yet to see one or know where it goes.
- Am I overlooking anything else?
Thanks again.
Click to view attachment#1 yes use gentle heat to soften its grip to the metal arm while twisting and pulling. URO and/or AA have replacement grips.
I really wish I had my part in front of me and/or a better memory.
I think on #2 that those threads are wrong and/or were the jury rigged solutions. I don’t recall there being any separate spring.
If I recall the pawl engages the ratchet sector and the tension in the cable provided by the springs on the caliper levers is what holds the pawl in contact with the ratchet when under load.
Then when the lever is lifted, the rod and the flat piece of the rod engages the pawl to release the pawl from the ratchet sector.
What causes the failure of the flat metal piece was depressing the button before lifting the lever. If I recall, that leads to the flat portion getting bent and jammed without contacting the pawl correctly. The other contributing factor was not lifting the lever slightly to take the load off the pawl - this resulted in the button and the flat metal piece being jammed into the pawl and loaded up more than it could take as it tries to push the pawl out of engagement with the ratchet while the cable was holding everything under load.
Long way to try try to say & to convince my memory that there wasn’t a separate spring that was missing from PET.
The part your calling the clinch pin is easily found in hardware supply houses - just use a small Clevis pin and clip - or go whole hog and fabricate your own riivet and staking tool to make it look just like OEM.
The whole early park brake lever is pretty neat how it all works. Very Germanic. It’s a shame it was sort of fragile and so prone to failure when ham fisted, more force is better, Americans got their hands on it. When I had my Miata, my dumb ass friends (said endearingly -
) would always try pressing the park brake release button before lifting the lever slightly to take the tension off the pawl. Would result in a loud pop and then the lever releasing too quickly. Some things never change
but the Japanese anticipated this sort of use and the lever always held up despite the abuse.
