I have a four wheel drum set up and thought I would check into the Praise Dyno brake shoes before considering converting to disc.

427L88 uses them on his 67, look him up or email for his thoughts.

I love them, with stock shoes I had to really stand on it at the end of the track to stop - switched to praise and now I can actually coast-apply-coast to the return road!

Superb. Quantitatively, drums have a coefficient of friction of around 25-30%, discs 75-80%, Praise shoes around 60%. That's what they told me, and it mimics my 'seat-of-the-pants" experience. Not quite discs, but much, much better than stock. The biggest difference I noticed was easy around town driving. Guys have driven the car and thought I had manual discs in front! But it's not quite discs.

Like drums though, you still have to be cautious of stomping the pedal at the end of a 1/4 mi doing near 120, you never know which whay the car will jump if you forgot to self-adjust the brakes prior to the run. But at least I don't get a "pucker factor" and have to rapidly downshift the car anymore.
BTW, the shoes have around 15k on them and are still mint. I'm figuring another 10K.

Gene, do they have a website? Did you get them thru a dealer? How was the pricing? Are they available for the front as well? Ah, questions, questions.... smile.gif

Here's their website:

I have their shoes on all 4 corners of my 71. (non-power drums) along with their hardware.
Been on for about ten years, no problems.

I will second what Gene said. Much, much better than stock. Before anything above 50 mph was scary. :eek: I can lock 'um up now. Does not fade as bad as stock stuff. Definitely money well spent. graemlins/thumbsup.gif

Justin, I bought a kit from them, shoes for all four and stiffer hardware ( springs). This was five years ago, and I beleive the cost was around $240. I was not aware of Stage I, II or II at the time. You'll have to have the drums turned is all. Otherwise it's a bolt on deal.

Mine don't lock up, but I attribute that to the difficulty of getting a good bleed with DOT5. While it repels water, IT LOVES AIR!

Thanks for the info guys. I'll check 'em out!

Ok, I checked them out. I liked the looks of the Stage 2 Disc and Drum combo. I already have a set of disc spindles from an old '69 Chevelle parts car. The only other thing I would need would be calipers, hoses...and maybe a porportioning valve.

BUT, for some reason, I get no price quote on a Stage 2 kit for my application. I see no quote for that kit on ANY application. I tried to see if I could email them. They don't accept emails anymore. :confused: Guess I'll have to call them.

Anyone get a Stage 2 Disc and Drum kit? If I couldn't swing that, I think the standard Stage 1 four-wheel drums look pretty decent for the price. Thanks guys!

I got the stage 2 disc and drum kit - very happy with the results, now about 2 yrs old. Make sure you follow their break-in procedure, too.

Xtreme, how much did the kit set you back?

It wasn't cheap (several hundred), but very effective. Don't remember exactly what I paid, but I could try to find the receipt if you really need to know, it would just take a little time.

Gene (427L88), make one of these and solve your brake bleeding problems: www.bmw-m.net/TechProc/bleeder.htm (http://www.bmw-m.net/TechProc/bleeder.htm)

Wooderson, neat! Thnx. Problems started when I put a line loc in place. DOT5 is hard to bleed , it really wants to suck air back in. Pressurization would cure that quick!

THNX!

I bled all four wheels on my car that was completely dry in about twenty minutes. I did temporarily use a special plug in the proportioning valve to lock the shuttle valve from moving. Sometimes that can be a problem while bleeding. You will have to modify another master cylinder cap, and if you have a dual reservoir setup, you'll have to tee through the cap to get both sides. I'll never go back to the old way.
