I have a 2010 Grand Caravan which eats brakes.

In 75.000 Kms they have been done three times.

I'm wondering if slotted and cross drilled discs may be better than OEM?

It is mostly city driving problem was so severe dodge doubled the initial warranty on brakes figured problem may be heat generated ???

    I highly doubt they'd help and suspect they may make your pads wear faster. How does your car eat brakes? As in the pads wear faster than expected? They wear unevenly? What type of pad is used? semi-metallic? ceramic? How's your driving style? Do you carry large loads in the van?

    Wow, there is either something wrong with the car or the main driver rides the brakes constantly. People who ride the brakes really go through them.

  • Does "done three times" mean the brake pads were replaced, the brake rotors were replaced, or both?

  • Question. Does the driver use their left foot or right foot to press the brake pedal?

No, you are best off with blank rotors(no slots, no holes) just like stock.

  1. Slotted rotors are more aggressive on the pads.
  2. Drilled rotors are plain dangerous unless they are a good quality(read expensive) that were cast with holes in place not drilled after the casting. generally, cheap drilled rotors are for looks only. They are also less efficient in general as contact surface is less and heat dissipation suffers as well. They are also more aggressive on the pads.

Here is what you can do:

  1. Pick up good quality Ceramic pads - they will last longer compared to the low quality organic or semi-metallic pads.
  2. "turn" your rotors at the brake shop of there is thickness left to do so safely( shop will know if it's a good shop ), or get new ones - don't need any fancy ones - rockauto.com has great prices and that's where I get most of my parts. Brands like Centric or PowerStop are more then enough for daily driving. But do get blank without any slots or holes.
  3. Adjust your braking habits - this will just improve life of your pads proportionally to the quality of your pads :)

Potential reason your pads are eaten away so quickly:

  1. They are cheap organic pads that shops sells you and don't last long.
  2. Your rotor surface is in bad condition and that affects the pad life as well.
  3. You are hard on your brakes.
  4. You drive down a long hill every single day.

  • Do rotors with holes drilled develop cracks?

  • @IhavenoideawhatI'mdoing It depends on the quality of the rotors and how hard they are run. They might, and assuming an average level of attention to details for a typical driver, it's safer to just get blank rotors.

  • The whole point to slotted or drilled rotors is to vent gas and dust created under severe braking loads, slotted is the preferred method these days....autoanything.com/brakes/…

  • @Moab This was the point in 1960-70, when brake pads caused severe outgassing. Not any more. Here is example of the F1 brakes, ther eis no slots or drills... 40.media.tumblr.com/tumblr_lwiihh3Isq1qk65n6o3_r2_1280.jpg

Drilled and slotted rotors are used for racing cars or road cars driven very aggressively and perform well in rainy climates.There are many benefits of drilled and slotted rotors and they are a bit more expensive.

  • Unless the vehicle is going to be used in high speed situations, those slotted and drilled rotors are a waste of money.
