General Brake Questions

[16-in-Dec]

We are going to work on the Tate's FJ 40 brakes this weekend and I need a couple of questions answered.

Set up 1969 Drive train and frame, we are staying with Drums, 1972 Tub so it will have power assist.

I read some where that if you intend to upgrade to disc (in the future for tate) you need to replace the brake lines on the 69 with the larger lines from a 72 forward. Any truth there?

I can't see any reason why the 69 brake lines wont work with a booster, is there?

Tate said that you can go with a 4 runner booster instead of the expensive 72 a rebuilt factory. Which one has the correct mount and throw?

The rebuilt factory boosters I see are 300 to 400. Is there a better source?

Brake hoses - Where is the best place to find replacements?

Sorry so many questions but I have no experience in dealing with brakes other than bleeding and replacing pads.

Thanks

The lines are of the same diameter AFAIK, but the fittings at the ends are larger (10mm vs. 9mm) Keep the lines, cut off the ends and replace with 10mm ones. Good sources of these are junkyard Toyota cars and trucks. You'll need a good double flaring tool to reinstall them, buy name brands like Gould, Snap On, Matco, etc. (search eBay and search the Outfitting section here)

I can't see any reason why the 69 brake lines wont work with a booster, is there?

No, there isn't but if the 69 has a single circuit, you'd want to make it a dual circuit. Mo' betta.

If you have a dual circuit already, just rebend the lines since the booster will move the master forward a few inches.

Tate said that you can go with a 4 runner booster instead of the expensive 72 a rebuilt factory. Which one has the correct mount and throw?

Any of them do before the Tacoma came. More importantly they have the same firewall and master cyl. bolt patterns.

The rebuilt factory boosters I see are 300 to 400. Is there a better source?

Rebuild your old one at Booster Dewey (google search) for about, what, $175, or buy a used one off many newer Toyota cars or trucks from the junkyard for $15-$50. Make sure the bolt patterns are the same and the diameter isn't too large that it hits the clutch master.

Brake hoses - Where is the best place to find replacements?

I've had good luck at NAPA. I always ask for Raybestos.

Many 1969, and even a couple rare late 1968's actually have the 10mm fittings. Important to check though, 9mm fittings are now basically non existant.
