Project 1: E-brake
The Land Cruiser e-brake is a drum bolted onto the output shaft of the transfer case between the transmission and the rear driveshaft. The advantage is that there is but one set of shoes, adjusters, cables, etc. Less to go wrong. Probably, the trucks place in the military and outback contributed to the design. The one flaw is that the output shaft passes through a seal that lasts only so long. Once that seal fails, this technological anomaly becomes an unwelcome oil-slinger. Take a look, about midway, under any Land Cruiser and your likely to find the area to the rear of the transfer case a disgusting mess.
There are two parts that appear very much as any drum brake system will look. A backing plate with two shoes and a mechanical spreader (no hydraulics). Then the "shaft" drum, with a polished outside and splined inside, rides on the output shaft of the transfer. Here are the pics of my cleaning, painting and installing.
Finally the e-brake is back on the truck! There is still a little work to do (cable, drum) but it's good to see this kind of progress, albeit small.

This was the second set of caps I bought used on Ebay. The first set was NOT (as the seller suggested) applicable to the TLC (Toyota Land Cruiser). He was guessing that the part for the mini-truck might fit, and I thought so, too. This set however is the real McCoy. Rarer than hen's teeth! Got very lucky and scored on the price, too. So there was a small amount of road rash and rust to remove. Paint is black and the lettering is oh-so-perfect gold. So, black is easy, but how to preserve the gold? Still thinking... I don't want to paint over and re-letter... too hard. And the paint would never be as resilient, or good looking.
Project #3: Speedo drive.
You may recall the speedo drive gear discussion. To recap, there are a variety of gear ratios to accomodate tire size affects on the recorded speed. Toyota never intended a gear for oversize tires, but my intention is to be as close as the available parts will let me. I'll dispense with the details of the parts, and jump to the problem. My old gear is frozen on the cable! So, I've been soaking the union (slip fit, with key) in PB Blaster for two weeks. Time has come to see if they'll come apart... and they did with a light tap (thanks Nan). I'm a bit worried that the driving gear will wear this new plastic part (information about this modification is anecdotal, at best!). Well, after assembling the new gear and test fitting, all seems (statically) okay. A few spins of the drum and it seems to turn smoothly. No pics of the trial fit... sorry. Next time.

Second: When my truck was delivered in late June 2005, the seller included a new e-brake cable as the e-brake was frozen (recall the "slinger") and he was pretty sure it was a seized cable. It wasn't and I was able to get it working when I replaced said oil seal. However, this part is the very first new or used part ever stocked for this project and it has been waiting patiently at the bottom of a Rubbermaid tub for its moment to shine. That time has come! Next time... Different Bat Time, same Bat Channel.
