Brake Pads

[CougFan]

I have owned my 2019 Lariat since October 2022. It had 13,000 miles on it when I bought it and I just did an oil change at 19,086 at the local Ford dealer. On the multi-point inspection form, they listed the brake pads at 4-5mm on all 4 wheels. How could all 4 brake pads have the exact same wear with 60% front braking and 40% rear? Were they just trying to get me to buy new brake pads from them? He didn't push it, just said I should replace them next oil change. Are the stock brake pads so bad that they have to be replaced before 25,000 miles? I am not a left foot braker so don't ride the brake pedal and I don't brake hard, however, I don't know the history of the previous owner's driving habits.

Any guidance would be appreciated.

Thank you

The Ranger is designed to provide equal braking action on all 4 wheels- vs old school 60/40.
I am not sure at the moment what a new pad thickness is - but 4-5 mm is about 1/2 wear

Where did you see this? If that were the case the rear ABS would be constantly activating with no load in the bed. You'd never ever want equal force in the back except in some rare cases such as the Porsche 911 where there is a lot of weight on the back end and wider tires to boot. Then you could maybe approach the same amount of force, but for a truck, no way.

The rear pads are smaller than the front, and the rear is a small 1-piston caliper as opposed to the 2-piston units on the front, so the brake bias is still towards the front.

I'm at 40K and I'm just now starting to think about pads, and that's with hauling a heavy RV around a bunch.

I would double check that yourself. When my 2019 had 35,000 it was at 9mm in the front and 8mm in the back if I remember correctly. Sounds like the place you went to might want some extra cash

I doubt it's 50/50 under normal braking. That would be odd with it being lighter in the butt AND when you brake that gets worse. I could not find what the exact split is in any of the service info I have on this truck :-/ Just an assumption

That said; if you make traction control kick in; the rears are going to activate separately from the front. That might account for the even wear from and back.

From the owner's manual, " If your vehicle begins to slide [or spin], the system applies the brakes to individual wheels and, when needed, reduces engine power at the same time. "

That's wearing too fast?...my 106K mile 2019 still has 8mm pads all around...

The pads should last around 40k or so, but the previous owner may have been a brake rider so...

You're being ripped off...my 106K mile 2019 still has 8mm pads all around...

Your pads outlived your transmission? Jesus.

This here, I had to replace my wife's rear brakes at 60k on her Subi due to traction control. The front pads still had about 50% pad left on them.
So depending on how vigorous of driver you are will determine the pad life on the rears.

Wearing out brakes requires stopping, and given how quickly you rack up the miles I'm not sure that stopping is something you do a whole lot.

FWIW, all the vehicles I have had with stability control have worn out the rear brake pads before the fronts.

By This,

We do not have the old school proportioning valve; the ABS module now controls the pressure distribution between Front & Rear.
If you are attentive to the operation, you will feel the truck squat down some when heavy braking vs nose dipping.
So, in theory equal wear on brakes, some have reported rear wearing out faster, so either park brake dragging or defect in the system.
Every driver's different in braking habit and big city stop and go traffic, I lived in a suburb of Chicago, and it is brutal on brake pads. I had 22 stop lights between home and O'Hare it was that or add time to the commute to get to I-95 and pay the tolls. So, with my old car I would get about 2 years max on a set of pads. 19-mile drive and 45 minute minimum to max 2.0 hours each way.
I-95 added 15 minutes and lots of quarters back then.
What made it worse, everybody had the light changer box, so the light would be green then switch to yellow quickly, cause someone in the intersecting road changed it.

Electronic Brake Force Distribution (EBD)

On initial application of the brake pedal, full pressure is applied to the rear brakes. The ABS module uses wheel speed sensor inputs to evaluate rear wheel slip. Once the rear wheel slip exceeds a predetermined threshold, the ABS module commands the HCU to close the appropriate isolation valves to hold the rear brake pressure constant while allowing the front brake pressure to build. This creates a balanced braking condition between the front and rear wheels. If the rear wheel slip continues and exceeds a second predetermined threshold, the ABS module commands the HCU to open the dump valves to decrease the rear brake pressure and allow the rear wheels to recover. A slight bump sensation may be felt in the brake pedal when EBD is active. If the ABS is disabled due to Diagnostic Trouble Codes (DTCs) being present in the ABS module, EBD continues to function unless the Diagnostic Trouble Codes (DTCs) are for wheel speed sensors or the HCU solenoid valves. When EBD is disabled, the ABS warning indicator, the red brake warning indicator and traction control indicator illuminate.


FYI: To the OP, the minimum pad thickness per the manual is 1.5mm/0.059in both Ft & Rear Pads so this is most likely where the squealers are set.

Everyone's gotta stop...how you stop is the trick...

For what it's worth I don't recommend doing a roll in order to stop

Roll?

Roll?

Aka - California Roll - slow down and roll through the stop sign - got scolded by a cop who happened to see me do it - when I was younger of course.
He said Stop means STOP -it does not stand for California Roll
