Experiencing a “shudder” when braking below 20mph, TSB?

I’ve been trying to locate the thread for the TSB which discusses a vibration or shudder sensation when braking at low mph.

I believe it is TSB-0023-18 but I could be wrong.

The problem isn’t terrible to live with, but is definitely noticeable and while it’s under warranty (and before it gets a lift and wheels) id like to see if I could have the issue remedied.

Am I having the same problem as others, and can this be remedied with that specific TSB or a different one?

 

Try TSB (TCI-5093)

 

I had the same issue where it would shudder fairly hard below 20mph and down to about 2mph. I ended up replacing my brake pads and had the discs turned. It needed that anyway at 48K miles but that eliminated the shudder 100%.

 

Yeah shudders when braking are often warped disks. If it's the front you should be able to feel it a little in the steering wheel. If it's the rear (do rotors warp? ) you won't.

At higher mph, the vibrations happen too fast to feel, and when your almost stopped it might just feel like your driving over a small pebble every so often. But it's rhythmic and perfectly synced with wheel rotation.

 

I've got 46k on my truck and have already replaced the front rotors once. I was told that they weren't serviceable rotors which I find hard to believe.

 

If they're factory rotors they certainly are serviceable granted they're not warped beyond machining. Mine had 48K on them when I had them turned.

 

Rockauto are selling rotors for roughly $38 a piece.
Why would you want to machine rotors in this day and age.
Other than to diagnose (confirm) a rotor issue?
Once machined,..just change them...the cost of machining vs replacement if a false economy.
You will only need to change the machined rotors sooner as they cool less well....leading to more vibration in a short period of time.

 

Nothing wrong with machining rotors if done correctly and the rotors are within spec. Personally I would question a $38 rotor.

 

There is nothing wrong with machining rotors.
Other than just reducing the life of the rotor and helping it heat up that must faster.
And by the way,
Most rotors come from off shore, including the $100 ones.
Someone is just making more profit on the expensive ones.

Anyone that owned a GM product in the late 90's can attest to this.
The US made rotors warped withing 10000 and the Chinesium ones lasted double for half the price.
GM actually had a campaign on turning the rotors on car to shut the customer up until the end of warranty.

Look where that got'em..

 

Rotors are warranted? I thought they weren't due to being consumable wear items. Where did rotor campaign take GM?

 

Rotors ARE under warranty if not due for replacement because of rust or blued because of standing on the brake pedal in rain.
Machining rotors is a dealer ploy to shut you up temporarily...then when WORN out of specifications,..this justifies selling you rotors (hence wear item).

Problem is, if your truck/car has warped rotors.Machining is a quick cheap fix.

Tell you what, next time you need to have rotors machined at a dealer, offer to pay the difference between the shop time and new rotors.
Guess which the dealer will prefer?...
Yes, they can claim the machining time to the mfg, and justify the customer paying the difference.
Guess how the mfg make money,...thats right selling parts not paying a dealer to machine rotors..

Just some advice from the inside...

 

At Crown Toyota machining the rotors just comes with brake pad replacements and fluid flush. When the time comes I'll get new rotors.

 

You are correct it does reduce the life of the rotors albeit not by much as you are making it sound. It also reduces the cost of a brake job. Most rotors are made offshore but to different specs than the manufacturers require. I’ve used cheap rotors many times, not the same quality.
The dealers have absolutely no control when it comes to rotor replacement under warranty, if they are within spec and don’t have a defect. The guidelines are set by the manufacturers, Toyota in this case.

Sounds like you have a agenda. Not all dealerships are out to screw the customer.

 

Had mine I almost immediately with a warped rear drum. If I pulled the handbrake and just put slight pressure it would be very noticeable they turned it and said it was just out of round. All good now. Hope that helps.

 

Keep in mind that I was told this by Oreilly Auto parts. I think they just don't like turning rotors any more and would rather just sell new ones. The cost difference wasn't that bad at the time and frankly, I didn't want to put the effort in to find someone that would turn them.

 

They are serviceable if they are within spec. If replacing I would use the OEM Toyota rotors or a quality aftermarket rotor.
The number one reason for warped rotors is over torqued wheels. Use a torque wrench. I believe 83 Lb. pounds, double check that it’s in the owners manual.

 

Brought mine in to Toyota for my 5k checkup and they’re blaming this crap on my lift. I’ve had the truck 3 months, I waited because I guess I was hoping it would go away with use. They’re not going to fix it. I’m seriously pissed. Any suggestions on what I can say?

 

I had vibrations while braking at around 20k miles. I told the dealership about it when I took it in for the 20k maintenance. They replaced the pads and rotors under warranty.

Now I'm at 44k and it's starting to happen again. I'm just going to replace the pads and machine the rotors. Next time around I'll buy some aftermarket rotors.

I've been told the Tacoma rotors warp easily by my friend with an 06. Once he went aftermarket he never had any issues.

 

Small piece to this puzzle. When I load my bed up with a few hundred pounds of stuff, the shudder goes away.

 

This tells me it’s probably not brake related , more likely a driveline issue
