ATTN GMCBLU: Showing off my 21,000 mile DRUM Brakes...hehe

GMCBLU, You ask for more proof? I just got done taking pitures of my Kevlar Shoes and the Drum at 21,000 miles. I would still say there is at least 90% of the front shoes left! The back ones look like new! And not one grove in the drum!!!! What do other peoples shoes and pads look like at 20K miles ? By the way, that is with a lot of towing miles too.

Cool. Are those the upgraded drums? Or just the Kevlar shoes? (Does he even sell shoes only?) Everything I see about PraiseDyno's products is good, and I'll try to drop in on Mr. Ambrose on Friday on my way to the folks'.

Long shoe life is good, but I'm really more concerned about that one stop I may need to make to save my life (and saving my truck would be good, too), and an article by Muscle Car Review that PraiseDyno posted on their website gave me a good idea of their performance. I'm in no big hurry though, I won't be in the market for several more months.

Chris, thanks for the pics and the testimonial. This product has obviously proven itself to you. I'll be very happy if this setup can help me justify keeping the front drums (my decisions take time) because I'd like to keep the original setup, and I don't want the low-slung front end that disks would give it.

gmcblu, if I could post a picture on how well my burb stops with these brakes, I would Believe me, if they did not stop my burb (while towing 4500 lbs), I would not be happy with them. Those are normal $24 drums in the pictures. They have a process you can do to your brake parts that is suppose to really help disapate heat, but I don't know if it is really benificial. Besides, unless you are doing a lot of towing or autocross, I don't think you need it.

These are the new Kevlar shoes. They are suppose to be an even better material and no rivets! These are the new ones that Mr Ambrose sent me to replace the ones in the top picture. I have been lazy doing it, because of the 110 degree heat outside and I feel the old ones are just fine for now

You mean they're the same ones you can buy at any parts store? Or they're PraiseDyno's "normal" drums? (As opposed to the cryogenically frozen ones.) I read about the cryogenics process on the website and have heard of doing that to metal products before, like shaving razors.

I'm not clear on whether he sells shoes only, without his drums, or if they only come in kits with shoes, drums, wheel cylinders, springs, etc.

So which kit did you get and exactly what parts did it include? If you got new springs, explain to me how these much heavier ones are not any harder to install than factory springs (as he claims on the website).

The kit I got comes with the front and back shoes, and the heavy duty spring kit. The drums I used are cheap auto parts store type. The cryogenically frozen drums are a lot more than $24 You can also have your own drums treated. Im not possitive, but I think I was quoted $25 a drum here in Phoenix.

I understand that he has a newly designed wheel cylinders that apply more preasure and will make your manual brakes feel more like power brakes, but I don't know much about them.

The heavy duty spring kit didn't seem any harder to install than stock springs. The idea behind the heavier springs is so the return of the shoes is much better and there isno hang up.

Question

I'm still new to this group...and especially out of practice with drums...I need to redo my 70's real soon. Where do you get these Kevlar shoes? I'd sure like to use them on my truck. If they do hal of what you say, I'll be real happy with the stopping of mine

Thanks

My truck is a 3/4 ton and has power drum brakes. It has 34 years and 180,000 miles on it. It has never been wrecked. It tows a very heavy boat right now fairly often in mountainous terrain. I drive it too fast most of the time and have never experienced anything that I would consider dangerous having to do with the way it stops even in wet weather which we get quite often where I live. Unless I just get really bored and feel like blowing a few hundred bucks I am not going to install disk brakes . My wheels stay clean . My brakes work fine. The self adjusters work the way their supposed to.

I saw an article a while back on drilling brake drums.The holes were drilled in the contact area of the drums and spaced to keep the drum balanced.According to the article the drums and shoes heat and form a gas that gets trapped between them and reduces stopping power.The holes supposedly let these gases escape and help to reduce fade by keeping the drum/shoe cooler. They were advocating this as a way to improve brakes on mid-fifties cars that did not have disc kits available,but also claimed it would help any drum brake.Fading was also a factor in the authors decision to drill his drums.
I don't remember which mag I saw it in but I would venture a guess it was Custom Rodder.

I spent lots of money on various front shoes and drums and never could make them work well. When I lived in the Colorado mountains, I felt like I needed to throw out an anchor after a twisting and turning 5-mile downhill drive. I had a new master cylinder and high-dollar brake fluid, but it was matter of the brakes just not being able to dissipate the heat fast enough. Maybe finned front drums and Praise Dyno shoes would have made a difference, but the 86 front disc setup that I finally installed solved my problems, and I'm only using 1" thick standard duty rotors. If your drum brakes work well, I envy you because the conversion job is expensive and a pain.

mikep, something to remember, the 3/4 and one ton trucks have monster brakes compaired to the 1/2 ton ones. The 1/2 ton is dinky in comparison.
When i had the old 3/4 ton, once I rebuilt the front brakes, it stopped straight and true, however, I did get brake fade in the freeway durring panic stops.
i have spoken to an owner of a '68 3/4 ton Longhorn out in Cali who runs these kevlar shoes, and he swears by them.
I have actually been wondering if i should install the discs I have for the Longhorn, or just get these shoes. The disc set up is pretty fugly and rusted...pretty much everything needs replaced on them.
