Yes and no. D&S's can definitely be an asset if you drive routinely in hill country, or in stop-and-go traffic where the brakes are always operating warmer than normal. I do a lot of the latter, and I'm pretty sure the D&S's on the wife's Altie have prevented at least one accident. Brakes work by turning the car's kinetic energy into heat, so the bigger the difference in temperature between the brakes and ambient, the less efficient they are. The difference between flat and D&S isn't noticeable under normal conditions, but there are types of driving where D&S's are a definite asset. Choose accordingly.Ryantzer wrote: ↑Tue Nov 15, 2022 10:55 pmDrilled and slotted rotors are useless on a vehicle unless it's going to see track duty that requires increased heat dissipation from the brakes, and will actually provide less friction surface than solid rotors and greater likelihood of cracking them. If you're all about the poser bling, go for it, but don't mislead yourself into thinking you're installing parts that will improve the car's braking capabilities.
Personally, if I experience fade during "normal" driving I will first suspect low quality aftermarket brake pads or air in brake lines.VStar650CL wrote: ↑Wed Nov 16, 2022 9:21 amWe'll have to agree to disagree. Our old PT Cruiser overheated and faded constantly driving AR-7 and other roads in Ozark hill country. Put D&S's on it and never had another fade incident. Heat is heat, your brakes can either shed it or they can't.
The problem with the PT was a bloated vehicle equipped with brakes from a Neon. The only point I was making is that there are "normal" driving circumstances in which heavily-vented rotors are beneficial.fontana dan wrote: ↑Wed Nov 16, 2022 6:24 pmPersonally, if I experience fade during "normal" driving I will first suspect low quality aftermarket brake pads or air in brake lines.
A brake bed-in procedure is a good(and fun) way to gauge the ability of your brakes to shed their heat. No hills required. Cheap a** front brake pads will be smoking and fading after 3 or 4 passes.
Can't argue with that. It is a Chrysler product what do you expect eh?VStar650CL wrote: ↑Thu Nov 17, 2022 5:23 amThe problem with the PT was a bloated vehicle equipped with brakes from a Neon.

True that also.
Hey, calm down. @Ryantzer and I had a minor disagreement... about brakes... and @fontanadan made a valid point that led to Chrysler... brake jokes. Nobody's trying to change the subject or boot you out of your own thread. Please don't take it that way.
