2005 Trailblazer brakes/rotors question!?!??? Pads overheating?

[sellersm]

My son-in-law recently put on some kind of "high performance" brake pads (Power Stop 'hybrids' or something?) on his '05 Trailblazer. Today he tells me that he's smelling "hot brakes" when going down Powers.

He's thinking that some slotted/cross-drilled 'performance' rotors will help with this overheating of the brake pads...

I'm not sure what to suggest, if it were me, I guess I would've put on different brake pads to begin with...?

What say all the experts here?

Thanks in advance! I'll pass all the advice onto him. Gotta keep the grand-daughter safe in that Trailblazer!!!

Drilled slotted rotors will help but the first thing to check is for sticking calipers.

Also, if he just did it, tell him to wait a day and see if he smells it again. If it was during rush hour, could it have been someone else?

Thx. He says he did that. He doesn't believe any stick.

Thx. Did it a week or two ago. He's sure it's his vehicle.

What others said. Ask him if he pulled the caliper bracket and cleaned and lubed the pins, and replaced the rubber seals properly. If that checks out he 9 have sticking calipers. Not much else in there.
Rotors aint going to help until he gets it all working.
Did he bed the pads properly? Powerstops have a procedure for bedding them right.

drilled rotors are just going to warp faster.

You have not experienced what my wife can do to plain rotors. I got drilled/sloted just to give the rotors a fighting chance.

I ponied up for drilled and slotted just to try them out. They have a different feel/sound under hard braking, but they've been great for 20,000ish hard miles.

When was the last time he bled out the brakes; old fluid will cause the brakes to not fully release. I just bled out a friend's brakes who was having this issue on an '05 Jeep. Problem solved, and increased MPG as a result. Did he put these pads on used rotors without having them turned? Did he follow a bedding procedure after putting them on the car?

Edit: Are these pads designed to work with a specific type of rotor?

Thx! I'll pass this onto him. I do believe he followed the bedding/break in procedure. Don't know about bleeding the lines...

Now did he just do a pad slap? That right there would cause issues. Any unevenness, hot spots or whatever in the rotors will show up if you just do pads and not re surface the rotors. some get lucky and have no problems.
Gimme a call, I might be able to look at them soon.
