Its time to get to work on the LV.

Starter (its been sitting still 6 months)
Clutch master and slave
Brakes are dry - must have blown a cylinder

I am considering replacing the master cylinder, esp after hearing about Gene's accident. Is there a 2-piston (sorry, i don't know the term) master cylinder that bolts right up to the firewall and existing lines? (and where do I get one) Where is the best place to get a wheel cylinder or two?

I'm having a mechanic do the work, since I obviously cannot find the time myself.

That sounds really nice, but what would something like that cost? I cannot afford to swap axles etc. Is there a bolt up dual cylinder? Do I find it at my Toyota dealer, or do I order it from California...?
 
For the master cylinder, if you can get a LC 80 series master and booster, and get the unit to fit your firewall, clear the engine, and all that, then you would be off to the races. That's not a difficult problem to solve. The 60 series one would work fine.

As for the brakes, is your rear axle a semi or full float axle? If it is a full floater, then it is relatively simple to convert to discs using all Toyota parts: Rear Full Floater Disk Brake Conversion

I did this conversion on mine and it is extremely nice so far. I need to get a proportioning valve, which I mounted on my firewall. Givem me adjustable brakes for the rear, and that is nice to have when you load up heavy.

One thing: Does your parking brake go to the rear axle, or is it the transfer case mounted type? If you have the transfer case with parking brake, then the full floater conversion as described in the link above is perfect. If your parking brake cable goes directly to the axle, then you could do a similar disc conversion using Monte Carlo calipers, etc. Here's one of those types of conversions:

Then again, you could put the stock monster drums back on, go with new wheel cylinders, re-surfaced drums hopefully, etc, but it's not much cheaper than the disc conversion if you have to renew a bunch of parts. In the long run the discs are easier and cheaper to maintain. Easier to check up on visually.
