Rumble when breaking between 60kmh and 50kmh
Hi all
In the past few months my 08 Sedan (auto) has developed a rumble through out the car while I am braking aggressively that only happens while the car is slowing down through 60kmh down to 50kmh.. I replaced my front rotors thinking that was a possible issue. and it is not a pronounced, but still happens.. There is no shake in the steering wheel, nor any feedback through the brake peddle.. Any thoughts? Thanks all! Forgot to ask also.. Anyone had any issues with the mounts on the Yaris?.. will be checking them out to see if there are any issues with them.. The one under the battery looks a bit tough to get a look at its condition with out having to remove the battery tray etc... Last edited by CB900F2; 10-05-2014 at 08:10 AM. |

the mount under the battery tray is often overlooked, i've replaced those on about 5 cars in the last two months.
Most people / mechanics do not bother to give it a good look. regarding your 'rumble' when braking... I'd check the RIM / wheel temperatures after a normal daily drive if a front rim/wheel is hotter than the other, it probably means a sticky brake calliper piston or a bad wheel bearing... same goes for rear wheels but IIRC they have drums at the back, right? |

I just properly read your post. I take back what I said. If you're not feeling anything in the brake pedal and you replaced your rotors then chances are it isn't your brakes. Maybe stabalizer links? Or bushings in that specific area of the drivetrain?

no worries
to add to the topic if it has drums on the rear they might as well need some looking at |

Hi Woops.. What was the symptom of the issue with the bad mount under the battery tray?

Checked rim temperatures after a drive to work and no real differences between each front and rear sets. Only like a difference of 2 deg c..

Have you checked the drums in the rear? jack up the rear and give each wheel a spin. Check for tight spots in the rotation. If it's free, give the e-brake one click until there starts to be resistance. It should be a consistent feel.

This exact think used to happen to me then I put aftermarket wheels on and got it serviced and it just 'went away' so I didn't question it
I love the back of my car, the front... not so much |

Update: After taking into account the various suggestions, I decided to purchase a set of new drums and the rumble is gone..
Might have been some run out with in the drums I assume... or maybe poorly balanced drums.. Bought some second line drums, to replace these defective Beck Arnley drums... |
