Punto brakes VEEEEERY sensitive.. different pads?

so our new (2016) punto has VERY grabby brakes. i only have to rest my big toe on the pedal and it slams to a stop just about putting me through the windscreen...its driving me nuts..

is there a brake pad that has less low speed grip on the disc. something that requires a bit more pedal effort to slow the car? maybe thought about going for a racier pad that has poorer low temp performance??

any suggestions? as usual the dealer just shrugged thier shoulders

hi, my 2013 TA has been like this from new..
I've just got used to it..
my wife can't stand it

are you in a damp climate.. the 1st stops when the discs have surface rust are the worst - they catch me out.

Seems to be the thing with modern cars. Older cars have analog brakes, modern ones are very much digital - they're either on or off.

They do take a bit of getting used to
Byt they do work well so you really do notice if something isnt quite right
Its fun when you get a newer model (mines a 2012)or a fiat 500 as a courtesy car and you experience very grabby brakes it all over again.

i find it infuriating! not everyone is a 40 kilo weakling incapable of pressing a pedal more than 1 cm.

Oh, thought this kind of things were from some brand, thought Fiat was good and nice as my old ibiza 99 (and my evo 2011), but I avoided cars that has that too sensitives brakes

I did not notice on the demonstration vehicle..

Having older fiats in the fleet makes it worse..as they can take a reasonable pedal force to physically STOP

Re: Punto brakes VEEEEERY sensitive.. different pads?

Hi My wife's 2016 Punto 1.2 has these exceptionally fierce brakes as well. I actually thought that there was something wrong with them. I took the pads out and cleaned them and put everything back. It was exactly the same as before. I think it might be a 'characteristic' rather than a fault.

Please don't do that, you would be in big trouble if you did and subsequently were involved in an accident.
If you want to try something try some cheap pads.

Oh yes. I completely agree. Please never be tempted to do anything to your car which might compromise safety. If nothing else your insurance company will be delighted to use it as a reason to invalidate any claim which might arise!

I've been thinking, for some time now, that these modern power assisted systems are introducing a potentially dangerous factor into today's driving experience. I'm old, in my 70's now, and "mess about" with classic cars quite a bit. Most of these have no power steering and many don't have brake boosters. Yes you have to be a bit more physical when driving them, especially during parking, but you don't get a big difference in "feel" if a power system fails (mostly because there isn't one!) On a late model modern car if the power brakes fail you need to react very quickly with a massive increase in pedal pressure to maintain the same level of retardation but if an electric power steering system fails (and as we Fiat owners know this is not unknown!) And the driver is not ready for it and knows what it's going to feel like then it feels to them as if the steering has locked up (it really does get excessively heavy, have you tried yours with the power off? - if you do be careful not to have an accident!) I tried it with my wife, in the middle of an empty car park, on my new SEAT IBIZA, she thought it was solid and said she didn't think she could steer it. You have to be ready to immediately apply a lot of muscle if this happens and that's where people come unstuck, they are simply not prepared for it so don't react with sufficient force.

So what do you think. Is there a problem here for the average driver who probably has little knowledge or interest in how their vehicle works? Or am I just worrying about nothing? Your opinions would be very interesting.

Re: Punto brakes VEEEEERY sensitive.. different pads?

Just throwing the belt on an old.skool pumped pas system makes it markedly heavy.. a punto losing its electrical assistance is even worse

I can only imagine what the brakes would be like..!!

Re: Punto brakes VEEEEERY sensitive.. different pads?

Some thoughts-Vacuum brake servo with diameter of 250mm could add around 170kg of effort to master cylinder piston.
I think the last brake pedal I measured gave a 2 to 1 mechanical advantage .
So if 250mm diameter servo fails the driver would have to put an extra 85kg onto the pedal.
