I know there has been a lot of discussion on which is the best material for transmission bands, but what is the newest opinion. I heard the new Kevlar material can be too aggressive, other material wears and leaves lint. Just trying to make the best decision on a rebuild of the motor and bands.

I think this issue has been beat to death. Main options are: Cotton, Wood & Kevlar. I have seen brake lining bonded to bands but do not recommend going in that direction. If you tend to slip the bands more than necessary, use wood which grabs quickly. I like Kevlar....going on 16 yrs. with no problems. A lot also depends on the condition of your drums. They need to be polished for Kevlar and should be for cotton. Wood is more forgiving. Suggest using a transmission filter screen to catch any fibers. The ball is in your court.

You'll get all sorts of opinions on this subject. If you are one who slips the heck out of your bands, you will wear cotton or wood fairly quickly. Kevlar won't wear nearly as quickly, but it shouldn't be slipped excessively either because the heat generated by slipping Kevlar can overheat the drums. So.....I am of the opinion that I should minimize band slippage, and if I do minimize band slippage, why do I need Kevlar? Kind of a Catch 22. I have heard cotton is the smoothest when it comes to engagement, but I've also heard a lot about poor quality of the cotton bands available today, so I have steered away from them as well. I use wood. Wood will not make lint to plug up your oil line.

Marvin, Les and Hal make great points to which i can completely relate to. After purchasing my car, one of the first things i did was to pull the cover on the hogs head to do a major inspection to see if i had any major issues i was going to have to deal with before putting it on the road. Being this was my first T, i didn't know any better and was just crossing my fingers that everything looked good inside. Much to my delight, everything was in great shape especially the drums which i was the most concerned about after reading here on the forum how expensive they were, and what was involved in having to replace them. The only thing i did notice is that the cotton bands were pretty worn and needed to be replaced, so i put that on the top of the list and never gave it another thought about what material i would use, till i added a trans screen. After adding the screen i noticed huge amounts of lint were being caught by the screen, even after multiple oil changes, and i found it gathering on the mag post like a cotton candy machine, so what would it do to the internal oil line? I decided to go to Kevlar, and now after installing them i think it makes me more aware of the way i initiate low gear and the overall way i drive my T. Just my 2 cents, good luck on any option you choose.

I relined my brake with Scandinavian only a couple of weeks ago. Previous Scandinavian brake lining lasted eight years.
Mark Automotive linings were excellent too, but no longer available.
When Scandinavian linings become unavailable I'll switch to wood.
I'd never use a lining that machines the drums every time you apply them. My observation is that short lived cotton linings and lots of lint are caused by driving technique. Some can't let go of the fact they're not driving a modern car.

John, why so abusive and antagonistic to other points of view?..Is it your car?

There's no rule that says you must use the same band material on all your drums - for me the natural solution for best service and security against breakdowns and brake failure is to use cotton band on the reverse, wood on the low drum and kevlar on the brake drum :-)
Reverse is least used so perhaps the miles until low and reverse bands needs change will be about the same?

I always used the old Scandinavia or Wards linings and they worked great. I have been using wood in my '11 now, and I have wood in the engine I am currently building. My bands have always lasted for many years, but with the Scandinavia I have always carried a spare band with me. You can change a regular band on the side of the road if you have to, but not wood, because of the flexibility of the material. I know kevlar is popular but personally I have never seen the need for it.

If you use a soft lining like Scandinavia or other major NOS band, or if you use kevlar, try to carry a spare and use the bands with the quick change ears. If you are going to use wood you'll end up pulling the hogshead to change them anyway so it doesn't really matter.
