Subject: FW: FW: BRAKE PADS -(edited and unified Reference file)

Mike: It was me who originally posted the rancho pads. I've used them and they get rid of the vibration that I had with my 94 4-door h/t. I also posted the information on the use of another pad that I was informed of by Huntington Beach Hummer 1-714-841-3999. Ask for Marty in service or Sylvia in sales and they will get the name and part number for you.

* Hi Eddie!
* What were the brands of your replacement brake pads, ie, name, part #? Were they OEM or???

We used NAPA # RAY.MAS-7122A. At the autoparts store they used their big cross-reference book and sold us brake pads that were totally the wrong ones! So we took the old pads and compared them and we found the number above. I think the dealer wanted $80pr and we got these for under $30 if I remember right. I'm sure there may be better (high tech) brake pads out there but these seem to work fine.

Many brake squealing problems can be just due to the brake pads not mating to the rotors properly. Driving slowly with the brakes on for a few minutes so called BURN IN, sometimes better seats the pads. There is also chamfering, which is grinding the edges of the newer pads.

PS. Here are some part #'s for alternative brake pads..ones recommended. Anyone have alternative airfilter #'s...besides the $150 one from dealer? Any and all part #'s that would benefit the group..

NAPA # RAY.MAS-7122A ~$30/pr compliments of Eddie
Onadine Brake Pads #MKDT203 ~$90/pr

**You might also want to try to put on that none squeek liquid on back of pads**

Huntington Beach Hummer uses the Onadine pads which eliminates the squeeling tones. It is a carbon-fiber-metal composition. I called Jim at 1-717-841-3999 for this info.

Just wanted to drop a quick note about brake pads to the list. I just picked up a set from NAPA (same part number as in the FAQ) for 30.00. To my surprise this included a LIFETIME WARRANTY. Simply bring the old pads in and they will give you a new set, no questions asked. Quite a deal in my book. I'm going to install them this weekend, and will be sure to post back in a few weeks on how they are holding up.

Be sure that you get the 7122A, one pad is bigger. The 7122 both pads are small. I am on my second set, I got 35,000 out of the first set. Be sure to clean or replace the caliper pin(#12342339).Several owners have said that one pad was wearing much faster. The caliper must float on these pins to get even wear. When I changed the pads all 8 had about 1/8" left. I think the rotors should be turned, even if they do not look as if they need it. The reason is it gets rid of any glaze and it gives the pads a new surface to seat on. I turn just a few thousands, just enough to clean them up. Be careful the brake shops will take off alot more. Yes the second set of pads was FREE, that is a warranty.

Recently, and over time, many threads have posted regarding why Hummer brake pads often wear rapidly and different options on replacements. While at the AMG engineering facility a few weeks ago I realized that the brake system was a Kelsey-Hayes product. Recently I was at the theater with an engineering manager from Kelsey. We were talking about the Hummer and got onto brakes. He provided some insight into possible causes of short friction media life:

1. KH originally designed the braking system with a lower vehicle weight specification. Since then the vehicle weight has increased significantly, therefore, potentially increasing friction media wear.
2. Civilian vehicles friction media may wear faster than DOD vehicles due to possible different friction medias used. DOD vehicles being more metallic based and civilian vehicles more organic. It should be noted tha KH does not make the friction materials for the brake systems.

Was working on another Hummer's brakes today, so I took a couple of pictures for the "database". This one is of the 7122A pads where one side is larger than the other:
