#2 of 77 Prius Brakes issue by smt1 May 11, 2006 (2:05 am)
I own a 06 Prius. After about the 2nd week I noticed that when you apply the brakes and right before the car comes to a complete stop, you hear a noise coming from the brakes. It seemd to be a clunk or something like that. It does not always make the noise. The dealership said it is no problem. I just wanted to see if anybody here has experienced the same sound.

Replying to: smt1 (May 11, 2006 2:05 am) The friction brakes don't take effect until the final 20 to 0 mph range except in an emergency or hard stop. This is what you likely heard/felt. I also notice a whirring sound as they start to apply. It's part of the Prius regen braking system. It likely will save wear and tear on your brakes in the long run. BTW they stop great in emergencies.

Replying to: kdhspyder (May 11, 2006 8:39 am) Thanks for that input. Beats the dealership saying that did not hear anything.

Replying to: smt1 (May 11, 2006 2:05 am) Our '06 does exactly the same thing - a "clunk" sound that occurs on strong braking just before it stops, and again just after startup from a stop - but only under certain conditions, not all the time. I finally concluded it had to do with the regen braking, and/or the engine cycling, and decided not to worry about it. I worry even less now that I know my car is not the only one....

Replying to: kdhspyder (May 11, 2006 8:39 am) I have a 06 pruis, and last night it did not stop when and where i wanted it too. the road was wet, and i stopped hard so i expected it to slip a little, it always does in the rain. I have about 25000 miles on it, but the tires are not at all bald so i can only assume there is something wrong with the brakes..... and i just had it in for the 25000 mile service check. Has anyone else experienced this?

Replying to: wkogler (May 16, 2006 2:57 am) Tires don't have to be bald to have poor braking traction in the rain. Tire traction is the problem in all these cases, not the brakes. The OEM tires were likely chosen because of their low rolling resistance, not traction.

Replying to: typesix (May 16, 2006 9:10 am) Doesn't the Prius have anti-locking brakes? Shouldn't slide at all if it does. Replies to this message: kdhspyder (May 16, 2006 2:20 pm) stevedebi (May 16, 2006 3:26 pm) dmathews3 (May 17, 2006 11:47 am) typesix (May 17, 2006 10:30 am)

Replying to: dmathews3 (May 16, 2006 2:10 pm) ABS has nothing to do with sliding. If you are going sideways on ice ABS on any vehicle is of no use, it only helps to keep the brakes from locking

Replying to: dmathews3 (May 16, 2006 2:10 pm) "Doesn't the Prius have anti-locking brakes? Shouldn't slide at all if it does." Actually, there are situations in which ABS is a disadvantage. Gravel comes to mind; a vehicle with ABS will stop slower in gravel than a vehicle without ABS. Replies to this message: dmathews3 (May 17, 2006 11:47 am)

Replying to: dmathews3 (May 16, 2006 2:10 pm) If tire has poor braking traction, the ABS will keep activating to prevent wheel lockup but it will not reduce stopping distance. A tire with better traction will reduce ABS use and reduce stopping distance.
