And yeah the 5.0 is the newer version. As per Hawk: Hawk Performance said: The HPS 5.0 compound is similar in application with a strong focus on improving the already great properties of HPS. This compound offers stronger fade reduction, increased stopping power, easier modulation, and a decrease in wear, noise, and dust. In short, this compound can take more abuse while maintaining great street friendly performance characteristics!
Owner reviews for brake pads
Currently I have the Power Stop Z23 rotor/brake pad kit, which has worked really well. Originally I had bought some no-name pads/rotors off of Amazon that wore down within 9 months somehow, so I decided to spend more on the Power Stop kit for peace of mind.
i have an 80zx with an sbc swap, i’ve rebuilt all 4 brakes, replaced a master, swapped coiled did bushings replaced u joints
BRAKES : 312mm brake conversion Stoptech slotted rotors Akebono Euro Ceramic brake pads
I've been running Centric for a while. Good price, not much dust, they work ok. Not much grab when very cold (ambient temp below 40), but they warm up pretty damn quick, so not a huge deal. Never heard a single squeak, so 10/10 for noise.
Just replaced my PP pads & rotors. Hawk HPS & EBC RedStuff are both decent ceramic pad options. Shopped around quite a bit and never had the Brembos recommended. I went with Zimmerman blank rotors & Hawk HPS pads. No complaints + expecting less dust!
I put Duralast gold's on all my vehicles. Got a good warranty and come with all clips and brake grease you need. They're ceramic also, so quieter and more smooth braking and significantly less brake dust. Last quite awhile (1-2 years) as long as your not heavy braking all the time. And they're not too expensive either, moderately priced. Plus a bonus, they're black and match my paint.
I have the 1521’s, and will add another data point - less initial bite, great modulation. No dust, No noise. Overall I’m happy with them, but will continue to experiment - next round of braking components - floating/2 piece rotors and new calipers.
My stock rear brakes never made any noise. Recently replaced rotors and pads - went with Akebono Euro Ceramic - and now have the same "clunk" you describe. Usually only first thing in the morning when I back out of my driveway and then roll forward and brake.
My biggest issues with older trucks: 1) Emissions choked stock engines and/or the TBI motors in the GM trucks which eat valve stem seals 2) Brakes. My Dad's '88 C2500 never felt like it had enough brake when towing a reasonable load, even with trailer brakes.
