    :frusty:REAR**, ugh, first post on mobile.

    Hi all.

    New-ish member here with a question... I’ve had my 18 TRD 4WD OR for a week now and love it... but I’ve noticed a rubbing sound from the rear when I depress the brake and start going in reverse.

    It seems to only happen when coming out of park and starting to back up, and the ‘rubbing’ sound last for a second or two until I’ve fully let off the brake pedal. This is my first 4x4 truck so I’m not sure if it’s normal, a problem, or just a symptom of the rear drum brake system the Tacoma has.

    Any ideas? It’s a brand new truck and I can always mention it at the 5k service unless it’s a non-issue.

    Hopefully someone can help, thanks!

    If there is a click noise combined with that rubbing, it may well be coming from the front disc brake pads. Mine came from the factory with the W shaped 'spreader spring (my term) installed outside of the pad, not between them as it should. I still get a light click when going from reverse to forward after the truck sits for 5 or more minutes. I traced that down to play between the pads and the caliper, no trouble there, just annoying.

    Wait until you take the back drums off and find a piece of heavy paper between the drum and face of the axle. Supposed to quiet brake noise according to the dealer.

    Thanks but this sound is definitely from the rear. Hmmm.

    Yeah, that's where I thought my noise was coming from, until I found it was from up front. Yours may well be the rear brakes. I have the same truck as you, with a long bed.

    Was it something wrong or just how it is?

    Both actually. The spreader spring was in the wrong place on the passenger side front brake. I fixed that but still have the click when I back up and then go forward. It amounts to nothing more than clearance between the pads and the caliper.

    I finally had to have someone stand outside of the vehicle to hear the sound and pinpoint that it was coming from up front. If yours is in the back, it may be just the brakes dragging before they release, which is common.

    The dragging would make sense, actually. My RSX would sometimes do that up front. Hopefully someone else has some insight, too, thanks for the insight!

    If this takes place when the vehicle sits for a few days, or after or during a rain, it may be due to rus on the inside of the drums, or the shoes absorbing moisture.

    My 2017 4x4 has developed a "rotational" rear brake grinding noise as I slow to a stop. First noticed it at 25K miles, brought to dealer was told pin holding brake shoe needed adjustment, no problem. Problem NOT fixed, returned vehicle to dealer, BOTH rear drums replaced, After ONE DAY, problem has returned, preparing for THIRD visit to dealer. I'm reading that rear brake drum problems are rampant due to Toyota's poor quality control on rear axles since they are in 'hurry up' mode to fill orders. Bad runout on axles results in out of true rotation on drums resulting in rotational grinding/rubbing brake noise. Also read of lawsuits being files over this issue. Anyone else seeing this? I haven't heard the noise in reverse, yet, like the OP.
