Why is drum to disc called an upgrade?

How do we get ABS for our 67-72 trucks?

ABS would be another upgrade. Why? Because they are supposed to avoid wheel lockup. I believe wheel lockup reduces traction.

You usually get better strength and effectiveness when you pull/squeeze/supinate, rather than push/press apart/pronate. Disc is far better than drum... physics tells us so, and actions speak volumes.

My guess is the aftermarket is shy of this due to potential liability, however according to this 5 year old reference:

https://www.pro-touring.com/threads/...ket-ABS-system

There are these options:

High end: Bosch system, price range 6300 tot 7800 euros

Mid range: BMW Teves M60 ABS price range 4500 tot 5000

But they tell, bosch is best by far and most adjustable.. all topteams on le mans seems to use it they said..

Smart money would be to find a newer truck with the goodies and dog rob the parts. You'll need sensors and so forth which will likely mean changing the rear axle. I don't remember how it was configured on my 2000 Astro van, which wouldn't work for you unless you had 5 lugs.

Just keep the drums!


Seriously though, my drums are all new, well 15,000 miles ago, and with power brakes they'll stop 'Ol Green pretty well. But I'm going with front discs on my Panel build.

Yikes! ABS on my vintage vehicle. Some are different than others.

"Re: Why is drum to disc called an upgrade? "

The plain and simple truth is because it is an upgrade . Some guys are just fine with drum brakes ...Some aren't

If your looking at doing 100' power brake burnouts ( which in an empty bed pick up isn't hard to do ) don't upgrade to 4 wheel discs ,You'll just end up smoking your trans or clutch .

Probably don't is the simple answer. ABS is designed for a specific vehicle. A lot of money is spent tuning for that specific truck. You can't retrofit and expect it to perform. I have wondered if an '88ish rear ABS only system might could be made to work, but I would not try it. You would have to have that axle to get the sensor and on and on. The only way that might be safe would be a chassis swap and keep everything-even then you are not going to have the same weight balance as the original vehicle.

A lot of people don't appreciate the engineering that goes into brake design. For example, they'll slap a master cylinder from a Corvette on their Buick or pickup, never mind that the Corvette has really close to a 50/50 weight distribution. And look what is done with a lot of the rat rods. Some of these vehicles are just plain dangerous.

That said, as long as the brakes are properly sized for the application, the ABS could be added, because the real function there is to limit brake lockup.

sensible driving is the best upgrade, sadly not an option for some people..

Thanks KB. I've had every excuse. Now next time I get pulled over I'll drop the glove box door and point to the SPID... "Look man, I didn't get the sensible driver option. Sorry, couldn't afford it when I ordered the truck!"

Nice get out of ticket free card!
