    Hello.. I have a 2012 Toyota Tundra Crew Max. I was told I need a brake backing plate and said I would have to do both sides left and right rear. Is this normal for a a 7 year old truck? the cost would be $2,700 dollars. Just making a rubbing noise when turning left.
    Any help would be appreciated.

    Like any high $$ quote, get a few quotes.

    I could be wrong but a brake backing plate are for drum brakes. Thinking you have disc brakes which does not apply.

    I assume your talking about the brake dust shields ? If so, what happens is that they get rusty and create “rust jacking”, causing the plate to distort. What happens is that the inner edge of the rotor rubs on the plate causing the rubbing sound you mentioned.

    The dust shields are located behind the hub and the rear axles need to be removed to get to the plates. This is a very expensive job. Best solution is to have the inner lip of the rotor machined down 1/16 to 1/8 inches

    Since you live on the east coast, yeah, pretty normal for rust to overcome the backing plates.

    Are you handy with hand tools? These dust shields are 92.00 each. My ass would be doing this myself.

    I wonder if this is what I am running into now. I have a metal on metal grinding/scraping sound (sorta like the rotor rubbing the heat shield). When I brake it goes away. I pulled the rear brakes down and checked everything I could think of. All parts look in good shape and no replacements are needed. I've even checked the front for good measure. I'm completely stumped and started perusing the forum for advice..

    OP, how did they check the "backing plate" or "head shield"? You can't just look in the whole way around.

    Edit.... 2016 Tundra TRD Pro w/ 78k miles. (Brakes were replaced less than a year ago. Yea, I think its been less than a year with PowerStop E36 Truck and Tow.)

    I'm doing mine now along with the wheel bearings. Where in the world did you find the plates for $92 each? All i can find is $200-$380 each.

    Stay away from that shop. Huge ripoff. As others have stated, that backing plate (ie. dust shield) is only $100-200. It's easy to do the swap if you have the right tools but even then a shop shouldn't charge you that much. If you were in San Diego, I'd help you do it myself.

    A TSB just explains an issue and how Toyota recommends to fix it. It’s not a recall. TSBs still cover the vehicle they are issued for, they are not saying Toyota will pay to fix it.

    morning guys. Update on wheel bearings. easy as pie to pull everything off. 30-40 mins each. new bearings, new break backing plate, seals o-rings etc. got the bearings off/on easily enough. But it looks like the spacer went a little past where the C-clip sits making the bearings a tad bit tight. I'm guessing this isn't good.
    Any advice?
