'07 Yukon XL Denali Brakes - General Questions?

[BSarteSr]

So i have had this '07 Yukon XL Denali since 2009, done brakes all around on it several times, always do ceramic pads with new rotors.

I noticed that the rear pads wear out sooner than the front, also that the passenger rear wears faster than the driver side too.

I have several older ('60's, '70's, & '80's) show cars, most having front disc with drum rear, so they are setup to use more front brakes than rear.

My question is there something different about the '07 Yukon? Is it setup to use the rear disc's before the front? Other wise I might have any issue with the proportioning valve?

Getting close to needing a new set of pads and rotors all around, so I need to plan my attack!

BUMP.....anyone?

On my Escalade, there is a slight bias towards the rear brakes engaging first. As for side to side, I recommend taking a look at the calipers to ensure they are not sticking. I would not expect to see different wear pattern on a single wheel if all is operating properly.

Good luck.

I think you have a problem. All brakes are designed to be stronger in front because they do more of the braking. That's also why front rotors and calipers are bigger. Mines usually wear down about twice as fast up front.

How many miles are you getting out of the pads before changing them?

That's what I thought, found it kinda odd that my rear brakes wear faster than the front.

Get about 30k miles out of a set of rear brake pads, buy the premium ceramic and always replace the rotors. Sounds like I need a set now, been hearing the indicators in the last week or so, have to check the calipers to see if they are working OK, but I don't seem to have any pull from one side to the other (assume that I would feel something when braking if there was a rear caliper not working the way it should???).

30k miles is quick for rear pads on these trucks. They should see 2-3 times that depending on how you are driving. My guess is the calipers are the culprit. They probably aren't releasing as much as they should. I recently changed the rear calipers on my wife's denali (I suspected they were dragging) and I saw a increase of 2 mpg. Prior to changing them the brakes seem to work fine, stopped well, no pulling left or right. I also flushed out all my brake lines. Brake fluid attracts water, over time that moisture causes corrosion and things like your calipers to fail. I didn't realize once you open a bottle of fluid you need to use it or dump it, even says on the bottle. I guess once it's opened it'll continue to attract moisture.
Hope this helps.

Not a sales pitch, but I did use this power bleeder and it worked pretty good. Got all 4 corners bled by myself in about an hour. Also recommend using it "dry", just air creating pressure. Downside is you need to add fluid more often, but you won't have a dirty bottle to clean when you're done.
