Pulsating Brakes
 

I have just started to notice a small problem with my front brakes. When I push the pedal down harder than you usually use for stoping I fell a slight pulsating in the pedal. Do you guys just think my disc are warped? If so I guess Im gonna get some cross-drilled rotors or slotted rotors. Thanks for the help.

sounds to me like your disks are warped.

Thats pretty much what I thought. Just wanted to make sure. Are there any big performance diffs. between a cross drilled rotor and a slotted rotor or do they offer about the same increase in brake performance?

I dont know man. I use the stock brakes. They seem to be jsut fine for me. I only use the car to drag so in not jamming on the brakes like an autocrosser would. I havent noticed a change in the brakes even after 20K miles and plenty of backing it down from 120. They still look new.

Just go with OEM.. I think slotted and cross-drilled arent worth the money personally..
Slotted are harder on your pads.. and Cross drilled you have a better chance of cracking..

I agree cross drilled rotors that are just OEM copies then drilled are not as good as the higher end kits that are designed to vent gases, not just to look cool. Brembo makes OEM replacement rotors, that are under 150$ with some good pads that is all you need! And they are not drilled which means more surface area.

When you buy nice stoppers it usually comes with the specialized rotor, be it cross-drilled or slotted, to be compatible with; so it's not harder on your pads.

i think cross drilled and slotted are worth it cuz it does cool it down. I have heard that the slotteed ones are more stronger than the cross drilled ones. ALso know that sometimes, its all about the looks.

If they are designed for that and not just drilled and routered OEM discs like most are.

Three things come to mind. You could have warped brakes or maybe you just need to bleed them. The other things is your master cyclinder. Maybe a bad seal.
