New 4x4 Tacoma Has Vibration When Braking

After axle tsb on mine..vibration was worse and more often...took back after 2 days...tech said they should have resurfaced or replaced rotors at the same time...2nd time rotors or drums resurfaced..problem has been gone since...if tsb is done make sure they include the rotors or drums

 

usually its the front rotors need resurfacing or since the trucks has less than 2k miles the front pads haven't yet bedded themselves in yet, this sort of thing happened to my truck eventually the front pads will wear into the rotor surface and become alot better

 

You can feel the shudder from the rear when braking ...front end had nothing to do with mine

 

that weird the rear drums are out of round already to the point they need resurfacing on such a new low mileage truck. usually Toyota trucks can go 200k miles plus without any rear drum/brake issues

 

Rotors and drums turned

 

I don't know. As you say, many new trucks need front rotors resurfaced; only for the problem to return. And there are literally millions of vehicles delivered where the front rotors on a new vehicle don't need to "wear into the rotor surface" as logical as that seems.

Somebody reported that after market disc brakes solved their problem (doesn't mean it's true or addresses the main problem). Others have reported that issue is resolved by TSB or shims (even on non-modified vehicles).

Not sure what the answer is going to be for me, but since the rotor resurface I've driven perhaps 100 VERY easy miles. The problem WAS virtually gone. But is returning......

 

According to tech the axles being out of round or spec causes the damage to rotors ..tsb23 rotor should be replaced or resurfaced...when they performed mine if you look back at the work performed sheet I posted they did not do this procedure...my vibration was still there i took back and they resurfaced and now my truck brakes smoothly as it should....i have felt a slight vibration occasionally but it is nothing like before ...so for me the tsb 23 and resurfacing of rotors has for now fixed my braking problems...may be different for other people on here but it fixed mine for now

 

ive had 4 Toyota 4x4 trucks and they do have finicky braking if all components arent functioning as they should, if the front rotors become glazed thru over heating the brakes it cause the high speed shimmy/shake, if the rears are out of adjustment the brake pedal feels soft/spongey there are alot of variables ive been thru with my trucks brakes but usually had to do with the front discs not the rears, my experience is that using OEM Toyota brakes parts and pads are far superior than any aftermarket parts, using TRD Toyota brake parts/systems would be a high performance option if needed

 

hopefuly they have resolved the problem, while its under warranty and you've taken the truck in for this issue it has been documented by them so if this continues to happen after the warranty is up you still have a leg up on them since you've taken the truck in to address it(the possible axle issue)

 

Yep....my 2016 did it and my 17 does it also. What was the final outcome? Did you let them do that TSB?

 

@Cl4aub ... still in the clear ?

 

Yes mine has been fine since the second trip to dealership...info i was told was the tsb was for 2017 2018 models but my 2019 fell into that tsb from mine having a late production date even though it was a 2019 they followed that tsb but didn’t change the rotors/drums the first trip...service advisor said they should have been because the axles being out of round cause the defects in the rotors...I should have pushed it for new rotors instead of resurfacing since I didn’t have but 1000 miles on my truck...but right now I am glad to have it back and so far it has not reverted back to the shuddering...every now and then I get a weird vibration but I think I am paranoid at this point...after tsb how has everyone else’s done

 

Haven’t had a chance to visit the dealership since they turned my brakes. Going to drop it off tommorow and mention tsb 23 so they will at least check my axle clearance. I will let ya know how it pans out but most likely won’t have any news until mid-late next week. Thanks for checking back in.

 

Done a quite a few sets of drums. Toyota usually calls them back to see what happened to them too.

 

Do you think it’s abnormally high? Perhaps indicating a part or manufacturing issue?

 

Not abnormally high going off of the average 200-250 cars running through the shop each day. I'd say about a handful of trucks a month, if that.
We're actually sending a set back today lol.

 

Man, thanks for your input on this issue!

 

Hey can you possibly take a peak at my drums and see if they look strange from the pic. I took pics of both sides and my drivers side drum looks dimpled/rusty and old compared to the passenger side. Could this be causing my braking issue?



passenger side pic is in the middle, 1st and 3rd are drivers . Why such a discrepancy in the amount of rust on a new truck's drums. Shouldn't they be evenly rusted lol

 

The face of the drum with rust on it doesnt matter. its the rear axle flange where the drum sits that has to be inspected for corrosion. there is also a tsb out for the axles being out of round causing too much space between the brake drum and axle drum flange.

we did a passenger side rear axle and drums today.

 

That TSB doesn't extend to 2019's though correct? If so have they extended TSB 000023-18

Thanks for the response btw!
