FYI-I received quite a few Pm on this setup and here is a Brief Update On the ACDELCO & Raybestos NEW “
S-GROOVE” SLOT DESIGN Rotors and
Hawk 5.0 Brake pads.
I installed this Brake Setup less than 2 weeks ago and just wanted to Break-in (Mate) these Brakes accordingly to manufactures Specifications before posting my initial impressions,while my experience has ultimately been Good thus far.
I must admit my initial thoughts were a bit disappointing because the Hawk 5.0 Brake Pads did
not respond or Grip like the Stock Setup which gripped quickly with the slightest Touch while
cold and the Hawk pads do require a bit more pedal pressure for quick stops,but do come through and stop on a Dime.
FYI-Beware that the OEM Stock Pads are Built to perform more on the Cold side versus High performance Brake Pads which perform lineal when Braking,so initially did not expect them to Bite like the Oem the or until Fully warmed up.
I noticed the past week the brakes are starting to Feel more aggressive as the days progress and gripped quickly with a moderate Pedal touch and are Performing much better than the first week which proves that the Bedding procedure sometimes may take weeks or up to
200-400 miles in order for the Rotors and Pads to start performing the way you would expect!
The only Negative so far is they are a slight Bit noisier than the Stock Setup when applying the Brakes Hard due to the “S-GROOVE” SLOT AFAIK
Conclusion- Its starting to get some of that initial Bite (Feel) that the Oem Pads had with Far less Brake Dust which is a Positive and overall a happy Camper with zero regrets.
I also performed a Brake system Flush once again using
Motul RBF 600 Factory Synthetic Brake Fluid for a peace of mind. Z
