I have a picture taken on my rear brake discs. Is it normal for the brake pads to not work across the disc? Or maybe the wrong pads were used

A few years back they reduced the size of the rear Brembo pads so what you are seeing is normal now. Originally they did sweep the whole rotor but FCA made this change for some reason.

Normal. Not sure why.

Thanks for the answer

There's a big thread on this, might have been 2020 or somewhere close to that when FCA ordered the new rear pads into production. And even if you buy new pads from the dealer, they will be the new style short pads.

For 2021 you don't get slotted rotors on the 4 piston front/rear but it's a full sweep of the rotor.

I swapped my pads to the Powerstops. They sweep the entire rotor.

Then I guess it changed in mid-year 2021, they have been using the short pad for a good while now.

My December built 2019 came with those pads.

Over 50k miles and haven't had to change rear pads yet--but fronts twice.
Maybe they want to sell more rear pads so they made them smaller.

 

[DevoBuzz]

I believe the smaller pads were installed due to noise complaints of squeaking brakes from customers.

I wish I could find that other thread we had on this, looked and can't find it.

Not sure what mine are. Dust free apparently. Cars bday is 4/26/2016 It had 10,500 miles on it when I bought it 1.5 yrs ago

*hopefully can put the whole cradle in the steel scrap bin by the time the rear pads are shot : )

Frame it tub it!

You may have Powerstops. Are you the first owner?

Very interesting. I guess the rears really don’t do much in Dodge’s eyes then?
Now why do some big Brembos have slotted rotors and some do not? My 6 pistons have one little quarter slot in them and that’s it.

Scat Pack rear brake issues ?

This is from a Charger forum & it looks like newer cars with 4-piston Brembos have pads that only sweep about 75% of the rotor's surface. Has anyone noticed this with newer Challengers? https://www.chargerforums.com/threads/scat-pack-rear-brake-issue.386056/ It appears new OEM replacement pads...

Thanks for the official document This seems to solve the problem, question.

 

[Mondingo77]

That’s odd. I have an 18 Challenger R/T Shaker with the 4 piston brembos and slotted rotors. Mine in the rear cover the entire rotor. Hmmm.

 

[Slidd]

Changed in MY 2019.

If one were to measure brake pad force utilization on the front and compare them to the rear, you would see the rear brakes are probably 15% give or take of the force needed to stop your car.

In fact, rear drum brakes are a perfect match for front rotors in regards to successful and straight braking. However, with new wheel designs showing braking hardware, people saw rotors as being cooler than drum brakes, so the race was on to add rotors to the rear. The trick was how to make them 85% less effective.

Nonetheless, those of us who change our own pads/rotors prefer front/back rotor setup because drum brakes were always messy, the springs were a pain to install, and the automatic brake adjustment never seemed to work anyways(this system kept the brake pads at/near the drum material).
