    Thunk coming from rear when applying brakes questi

    Have any of you experienced a consistent thunk coming from the rear end when applying the brakes. Happens at any speed. The thunk occurs as the exact instance you apply the brakes. Release brakes and no thunk. Next time around apply brakes and thunk again from rear end. Just at the beginning of the application. Sounds like it could be the rear springs shifting. Of maybe a bushing?
    Thanks for any thoughts.

    are you running aftermarket pads? pads are

    known to shift especially if they don't have ears that line up perfectly in the caliper.

    other than that, you might be on the right track .....look at the suspension....

    just a wild guess......with the car on the ground....fully settled.....reach in behind the rear tire and see if there is any play in the spring.

    Yes! I actually thought it was the pads and coming

    coming from the caliper, but I convinced myself that it couldn't be that. So I started on the suspension kick. Since you mention that pads could be a culprit, I am now convinced it is the rear pad on the drivers side. I am running Axxis Deluxe plus. Suspension and calipers are stock. I need to walk along side the car and have someone apply the brakes. The thunk did appear at the same time I started changing pads around, stock pads, race pads and then Axxis Deluxe plus.
    Thanks for the reply

    Ears that down line up perfectly in caliper? I am

    trying to figure out what that means. I do not believe the outside pad is moving, I put anti-squeel on the outside pad and it looks like it is holding. The inside pad has triple finger type springs that insert into the caliper piston. So which are the ears you are refering to? Inside or outside pad?
    Thanks

    Figured it out, you are talking about the play of

    the ears against the caliper. Both inside and outside pad. At this point I think it is the inside pad moving around. When I reviewed the fit of the ears, it is not apparent that they have anymore play than stock, but I should compare them to stock.

    rat speak for the tabs on the ends of the pads

    the two tabs at each horizontal end of the pad that go into the braek pad carrier - if there is play in the that may lead to a noise - at least I think that's what the rodent is getting at..
