2013 Elanrta Brake Problem.

[HarryWA]

Greetings from NE Pennsylvania.

Sometimes on applying the brakes at low speeds ,as in coming to a stop,
the brake pedal vibrates and a rough noise is heard.
This was rare but now more often.

There are no ODB error codes.
Switching the ABS off at the dash board has no effect.

Not because of this problem I have redone the front brakes and the right rear
brakes this July; that is replaced the rotors. pads, and calipers.

The left rear was done earlier and I just pulled the wheel; the rotor and pads look okay.

Any ideas what to look at for this problem.

thanks HarryA

Hi Harry, and welcome!

That's a difficult one, as you've tried much of what I was going to suggest anyway. Does the car have an electric or conventional mechanical handbrake? If it has a conventional mechanical handbrake, on a quiet bit of road, maybe try stopping the car with the handbrake and see if the noise is still there. That should tell you whether the noise is coming from the front or rear brakes.

Was it doing the same thing before AND after you replaced the pads, and calipers?

Wondering if this vehicle has a single piston caliper, or two or even four? Notoriously difficult to check that all pistons are operating together!
I'd also check for the disc back plates being in too close proximity to the discs, check that all of the discs are rust free and there's no bearing play.
I don't think any UK vehicles have switchable ABS but I can't swear to that.

Thank you for the reply. On removing the ABS fuse so far I have not felt or heard any problems with the brakes.
I am hoping that helps solving the problem.
