Brakes are Fixed (from closed thread)

I kept having problems with rotors warping on one of my sedans. The drilled & slotted rotors weren't that much more expensive, so I stuck them on the car. That was 150k miles ago and the rotors are hardly worn. I think I have done two sets of brake pads during that time.

Just put new drilled/slotted rotors & pads on the 1/2 ton pickup... $159 through Summit Racing and 90 minutes of my time out in the shop (just because I also rotated the tires while I was at it).

This is just what works for me, and your mileage may vary. :)

I run nothing but ceramic pads. The semi metallic pads run hot and do not stop well when hot. Plus they are extremely dirty!

I have had nothing but good luck with the ceramic pads.

Ultimately the solid rotors have more metal mass to absorb heat and more surface area for friction. Outgassing is not an issue with modern semimetalic pads. Ceramic primary purpose is to reduce brake material making your wheels look dirty from brake dust. Ceramic also does not transmit heat well and forces more on the rotor. Google will find much to read such as this.

A couple of years back we had a big forum discussion (mostly cussin') ceramic pads and slotted rotors on one of the haulers forums I'm a member of.
Just about all the O/O that had went with them said they had heating and premature wear issues and went back to the good ol' HD semi metalic pads non slotted rotors.
One websites even had a sticky warning O/O members about those issues when using ceramic pads and especially slotted rotors on their service trailers and trucks.

That’s really interesting. I guess I lucked out into the semi metallic heavy duty with non-slotted non-drilled rotors.

Brake rotors go to the scrap yard, not the landfill...

Update:

Took about 3 hours at an Auto zone.

New calipers, new rotors, new pads, bled hydraulic system and it's all work all working perfectly. Better then new.

Just need to retorque the lugnuts after 50 miles.

Thanks for the idea to do it at an AutoZone.

Glad everything worked out.

Hi,

The rotors were only $60 Cdn each. It was cheaper to replace them than to turn them. I HATE that sort of waste.

HadEnough - glad you've got it taken care of! (We actually did do a brake job in a campground - a provincial park outside of Toronto - many years ago.)

Try to find a place that even has or knows how. Yup, easier and cheaper to replace with new.

The parts weren't the great aftermarket ones as I was hoping for. They couldn't source the good stuff. Just stock brakes with coated rotors and "heavy duty" auto shop pads.

You don't want those slotted and drilled rotors nor the ceramic pads.

Solid OEM style rotors and HD pads are better for this service.

Why is this?

From my reading people said the slotted and drilled with ceramic/carbon were better for towing and hauling. That they blew off the heat a lot better preventing brake fade.

I don't use my regular brakes like that anyway (I use the exhaust brake) but I'm curious what you mean.

All modern rotors are already internally slotted. Drilled rotor particularly on HD trucks will more than likely warp under hard braking with load. If the OEM does not use them........drilled rotors are for pavement princesses. Mass is what you want, it's not a race car.

Thank you, time 2 roll. Very interesting points.
