Title: Rear brakes wear out before front
Post by: asr1143 on December 10, 2020, 12:26:07 pm
Hi, I’m new in the forum and I just bought a abarth 595 competizione from 2017 full spec on the 6th of December 2020 with 44000km that’s 27k miles.

The car was serviced 3 times always by FIAT and the last time was in august, I realised the rear rotors and pads were changed on the last service and I was just wondering how come it happened first than the front brakes, always thought the front wear out first, my friend that came with me to buy the car checked the front disc and told me that the discs aren’t flat anymore and there’s a little metallic line around them and I would need to change them soon, the seller only did 2000km since the last service and I think FIAT would had changed the disc in the front if they were that worn out, I would like to know how many miles you guys have done with the front pads and discs and why the rear brakes wear out first. My English isn’t perfect hope you understood my questions.

It appears the you have not got a detailed service history of your car, so you cannot tell if or when your front discs and pads have been changed.
When you write little metallic line on the front discs, do you mean a lip at the outer edge? We have this on our current Abarth and it has covered 28000 miles, these are the originals. I appreciate disc wear is very dependant on driving styles.
The rear pads used to have a tendency to seize on, this would increase disc and pad wear. I push grease into the little rubber bellows to keep the slider pins lubricated. I have not seen this done at the service interval in the UK. This seems to work.

hi, i have the service history of the car, the front discs and pads are still the originals, yes i meant a lip on the outer edge, i was just surprised that the rear discs and pads were changed first than the front ones, but if you tell me that you have the same mileage than mine and you still have the originals so it might be normal i guess that they last that long, my friend told me that it has this lip around the outer edge and i have to change them soon, but the car was at FIAT in august 2020 for the 3rd service and they changed only the rear discs and pads and since then it has done only 2000km i guess if it was time to change front discs i'm sure they would have changed them.

The rears wear because of the ttc. Its constantly  applying the rear brakes to keep the front planted. Also worth noting rear pistons are rotary so if changing yourself the piston screws in, doesn't push.

Just had my car in for its first service this week. Only done 3500 miles. Front pads worn 40%, rear pads worn 50%. Discs are all good. Seemed quite high wear for such low mileage. As the car hasn't' moved much over the past year the dealer suggested that the corrosion on the discs (built up while sitting going nowhere) has had an impact on the pads as they wear it off. I'd like to think this is a plausible reason for the high wear, otherwise the Abarth eats pads which is not what I was expecting (and I don't have a heavy brake foot).
