OK, I looked very hard at the Wilwood & Baer systems, but did not think I would need this much braking as I am not going to do much more than some acceleration bursts and a bit of spirited driving around the hill country here in Texas (and Alaska next year)

So after a lot of research I am going with the Raybestos EHT Hybrid pads, which are Semi Metallic/Ceramic and the PER-300 Rotors F&R.

These rotors have degassing slots on the rotors and no drilling of the rotor. They do have a "Better PPV Rotor & Pad", but I did not want to deal with the dust of a pure semi-metallic pad like the EBC stuff I tried and took off.

I actually called and talked to one of Raybestos" engineers and he explained the metallurgy differences in the EHT & PPV rotors, which is what helped make my decision to go with the EHT products.

I looked into buying the AC Delco Specialty Performance Rotors as they are the Raybestos EHT product & I get jobber prices from a local AC Delco parts house. It is a bit odd though as AC Delco buys the rotors from Raybestos but uses their ceramic pads and not the EHT pads. However they could not match Rock Auto's price even though I get Jobber pricing.

All of the EHT products are available from Rock Auto and get our 5% discount, so I am going to order all of the parts at one time and get what I think is a good deal.

Total for F&R EHT rotors & EHT pads is $476.59 including freight & no tax.. I can not get that good of a deal from my local parts house using the AC Delco part #.

Anyway, that is what is going on my 6.2L Tahoe..

To answer the question of foreign metals, their metallurgy, heat treat etc. and my aversion to it, I worked as Global O&G Product Manager for the premier US roller chain manufacturer. For not being a metallurgist, I learned a lot about steel, how it should be made by the steel company and how the steel is made into parts my the product manufacturer and the differences between US steel & foreign, i.e. chinese & indian in particular. There are a lot of differences and none of them are good.

I currently build parts, both machined and cast, steel & synthetic, for a very specific piece of oilfield equipment and metallurgy as well as the synthetic makeup is paramount. My customers will not accept foreign steel products as they tend to fail at the most inopportune time and blow people into small peices since we are working with 5000 PSI to 20,000 PSI. Just my personal opinion, but each to his own.

Sounds like you did some good research! Haha let us know what you think when they come in and post up pictures of them installed!

I am in a similar situation, I have a 6.2 Yukon xl with 65k miles and a magnacharger and I am heading to Central America (from Montana) and I want to upgrade my brakes for better stopping power and have fresh wearables before a long trip into areas where parts may be difficult to obtain. I can't go with wilwood or Baer, even if I wanted to, since I swapped my 20" wheels for 17" wheels so I can get better off-road tires. They offer more rubber, better gravel puncture resistance and if I need a new tire in Central America, 17" will be easier to source.

Please let me know how your choices turned out for you...

I do see that wilwood offers an OEM caliper pad replacement. They also recommend a higher temp brake fluid... To stave off brake fade...

Thanks in advance,

D

Did you think about replacing your front lines with stainless steel ones? I just ordered some Power Stop K2070 for all four corners, ATE 706402 Original SL.6 DOT 4 Brake Fluid and 950.66002 - StopTech SportStop Stainless Steel Brake Lines.

I am hoping this setup yields better breaking than stock, I will know by the end of next week.

The per-300 are Chinese rotors FYI and the EHT pads are as well.

You could always do front wilwoods and just upgrade the rear. The wilwoods are amazing. I and others can speak from experience. Worth the $$ if you can swing it.

Yep, I found out that the Raybestos are ***** so will not be using them..

And Fiatdale, it is Wilwood or Baer.. I used Wilwood on all my race cars so am partial to them..

Back to the drawing board :)

Been too busy to deal with the Tahoe, so that turned out to be a good thing.. Now I will have the time to put some work into it...

Thanks for the heads up..

Definite upgrade when i did just the front. Really happy with the wilwoods i got. Pads seemed to last a long time too. Not sure what size wheels you have, but was a major improvement over 13" drilled and slotted r1concepts i had with 24" wheels. Just my 2 cents if it means anything.

Choo Choo-- thanks for the review.. I have always known Wilwood's are great, so that is the way I am going..with Wilwood pads on the rear. I already have the SS hoses sitting on the shelf.

Running factory 20" wheels so the 16's will fit..

Also going with the Goodyear Eagle Sport V rated tires..

Yeah the only downfall imo is the smallest wheel diameter you can go is 20". But thats really it imo. Good luck man
