Brake shudder?

[CB750F]

Raybestos? Like others said, u might have a problem somewhere as that is
not much millage to warp? Some vehicles have/had this issue, of going
through brakes, but the Ranger does not.
My truck 'bucks' when I come to a stop but when I put in neutral & stop
it's very smooth. So I figure it's the engine pushing & gears dropping???
No idea but annoying.

Luckily, I haven't had any brake issues but some like @t4thfavor have gone through multiple sets of rears including rotors.

I do experience what you're feeling on your truck. The rough downshifts are incredibly annoying.

@CO2Ranger , I missed @t4thfavor issue, but that must be something in the system
as rear brakes going is a bad balance I would think.
As for my 'pulsing' it's one reason why I like manual so much more.

Is brake shudder an issue with these vehicles? My 2019 with 32K miles developed a bad shudder while braking after they were warmed up.

Took it to local repair shop I know well. He said brake pads were fine but front rotors were warped. Because they were original, they had enough mass to turn them down, which he did.

Lasted a week and it's back to shuddering as bad as before. I don't tow.

At this point, I'm probably going to just buy new front rotors and install them myself.

Any recommendations?

Yes.

Both of my Rangers, my 19 & 20 had the rotors turned down under warranty. I do brake heavy because at times I drive it like a sports car.
I don't think it's acceptable though. Luckily rotors are not to, to expensive so if I have to replace them myself in the future no big deal.

I had more rear brake work done on this car than I had on my focus st in 4 years of heavy commuting abuse and track days…

Brake rotors don't warp. If you got them hot enough to warp, your truck would be burnt to the ground. You are experiencing DTV (Disc Thickness Variation). It is mainly caused by pad material depositing on the rotors. When pads are new or when really hot, sitting at a stoplight with your foot on the brake "cooks" pad material onto the rotor. Usually a light cut on the rotor and rebedding the pads, or new pads, will fix it. Also, as has been mentioned, lube caliper slides well, clean rust off of hubs, etc.

Just for clarity, in general when someone says "my rotors are warped" they mean that they are no longer straight in some way...

The rotors on my truck were turned and replaced 4-5 times (turned only once because I told them that was unacceptable), and were still brand new looking but 10 thou out of true using a dial indicator. They were definitely screwed up, and it wasn't the pad material depositing on them.

It’s almost certainly the rears. Total nightmare for me. I have replaced or turned them every 18k miles so far. Just picked up the truck again made Ford standby the 2 year parts warranty this time interestingly… Ford has updated the rear rotor in some way note the B revision indicator in the part number. Maybe this time is the lucky time

I was dealing with some braking issues with my 2020 Ranger, I thought for sure it was the front rotors due to the intensity of the surging since I was convinced I felt it in the wheel as well.

I had done some extensive off roading over the summer with one trail in particular that posed heavy braking challenges on the way back down. Since I had a friend there as well, I was often stopping and waiting for him to navigate an obstacle before I could continue so I was confident I had cooked some pad material on the rotors.

I replaced the front rotors and quickly discovered that the problem was coming from the rear, so I replaced them as well and the problem went away entirely. Including some pictures to show the difference in old vs new.

I went with the drilled and slotted rotors to test this summer when I plan to do a lot of trail driving again, I know there are downsides to them as well but I am interested to see if allowing gas and air to escape will prevent the previous marking I had on the rears.

Anyway, just wanted to share my experience in case you do a visual inspection and find a situation similar to mine! Or if the front rotor work still hasn't fixed your issue.

How many miles are on the drilled and slotted rotors? I’m very interested in seeing if that fixes the problem in the long run.

Yep, I'll need part numbers and where you got them from. After I did a traditional brake bleed on my truck it got somewhat better, but I had already put 5K miles on the messed up rotors because I can't take my truck to the dealer for a week every 2 months...

So far I have about 1500 miles on them, no issues at all and haven't been getting any excessive brake dust either. I have only daily driven it with them on though, so nothing too taxing for them but I also have not had any reason to suspect they wouldn't hold up to some abuse. A light to moderate trail will be in the near future for them though. This is the kit I purchased:
R1 Concepts Rear Brakes and Rotors Kit |Rear Brake Pads| Brake Rotors and Pads| Ceramic Brake Pads and Rotors |Hardware Kit |fits 2019-2021 Ford Ranger https://a.co/88Ce5c5

Purchased on Amazon (my link goes to them and the part number for the kit is 1PC.54156.42)and shipping was faster than they quoted. Also got the front kit and no issues with those either and the fitment and quality of the kits were great.

Had the exact same thing on the rear brakes of my 2019 with about 22k miles on them. Pulsing when braking and the same lines on the rotors you see here. Replaced with raybestos rotors and powerstop pads and all good so far. Do you leave your parking brake on when you park? I did and was wondering if that was contributing.

Still have a "grab" and clunk sometimes when stopping at about 5-10 mph. Clunk happens in gear or neutral so I think possibly brake related, but I've yet to figure it out. Front rotors don't seem to have any runout.

 

[Shane Bevel]

Oh. I should have mentioned. I replaced the pads with power stop heavy duty pads last time I replaced the rotors. Same issue 18k miles later.

I do engage the parking brake when I park...didn't even think about that being a possible cause so I appreciate that perspective!
