#2 of 73 Overly Sensitive Brakes
Sep 12, 2006 (12:11 pm)
I've owned Toyotas for 16 yrs; still drive a 2000 Camry. Since the day we got the TCH, the brakes seemed 'different,' overly sensitive. On slowly backing down my driveway, they almost felt grabby. Anyone else had that problem? Or is it just MY car may need an adjustment? BTW, love the car, despite center-console squeak. These both are minor and will be addressed.

I posted a similar message at greenhybrid.com but I was questioning the final couple of feet as I come to a stop when driving on public roads.
Mine seem to grab at the last possible moment as you come to a complete stop. I tried unsuccessfully to duplicate it for a technician when I had it in for other reasons. They said that they were behaving normally.
You have to keep in mind that the brakes at slow speed can be grabby, since you are braking "by wire" - there is no mechanical connection between the brake calipers and brake pedal. It is done electronically. At higher speeds (abouve 12mph from what I have heard), braking is done by using the resitance of the "generator" and this is used to recharge the batteries. In a panic stop, the mechanical/hydraulic brakes are engaged.
#4 of 73 TCH Brakes?

Today's NY Times (6-18-06, Auto Section, p18), says Road & Track ranks the TCH among worst for stopping distance from 60 mph. A rare negative report for the TCH. The TCH stopping distance is 136 ft, compared with 110 ft for Maxda RX-8, among the best. No mention of the non-hybrid Camry; did R&T test one? Can one shorten the TCH's stopping distance with different tires?

Granted that is 6 feet further than the 07 Escalade. However considering how much ground you're covering at 60 mph (88 feet per second), for my concern, the reaction time of the driver is much more critical than the 10 yards (about 1/3 of a second) difference in panic stopping distances.

I can't find this R&T article or the NYT article yet online. Do you have a link?
I'd like to see how the TCH did compared to the Camry LE, Honda Accord, Honda Accord Hybrid, etc. I wonder if the regenerative braking causes the longer stopping distances?
Well, I'm at least glad the NHTSA tests showed the TCH at 5-stars for front and side impact tests for all passengers. That will help offset some concern over stopping distances. And, though not possible in all cases, sometimes you can brake and steer around things, which is where ABS & VDIM come into play.

Not only would tires make a difference but also other factors... for example... the size of the disc and pads( more to grip)... profile of the tires( more road surface contact)... just to mention a few.
also comparing a TCH and RX-8 is like apples and oranges

136 ft is a reasonable stopping distance for a family sedan. If you look at numbers of family sedans (even performance ones) the stopping distances range from the high 120s to 130s.
Of course sports cars have shorter stopping distances- they have bigger brakes, larger tires, and stiffer suspensions.
If you want to see long- the Prius took 154' to stop from 60mph.
AFAIK, R&T tested a preproduction model.
The tires on the TCH are reasonable all season tires. Yes, you can improve the stopping distance with higher performance tires, but your trade off is a harsher ride and more noise.

Sorry, I don't have a link to the NYTimes or to Road & Track. I don't know if R&T tested the non-hybrid Camry. Does Toyota's hybrid technology reduce braking performance? Can I improve braking performance with different tires? Do larger wheels improve braking performance?

According to April '06 Motor Trend, Camry Hybrid 60-0 braking distance is 126 ft, much shorter than Road & Track's test of 136 ft. Same Motor Trend says Prius braking distance is 124 ft.
