View Full Version : Anyone change thier own brake pads in 500e?

In looking over the maintenance schedule for the 500e, I noticed there are very few items to address, and none of which have anything to do with the electrical components of the car. Things like, check tire wear, emergency brake, brake pads, CV boots & joints. These are all very basic maintenance items that should not warrant a trip to a mechanic or the dealership.

I'm wondering if anyone has changed their own brake pads? Is it more involved because of the regenerative braking? --- or are the service techs at the dealership trying to scare me into thinking I have to take my car into them for everything...they said there was a high voltage risk.....seriously?

The 500e uses the same brake components (pads, discs, calipers etc) as a standard Fiat 500, and brake service procedures would be the same. In general, you can expect brake pads to last much longer in an EV than in an equivalent gas engine car, because regenerative braking can be used to augment the braking function, allowing less wear on the mechanical brakes. The 500e has been around only since 2013 and it is quite possible that no 500e owners have needed to change their brake pads yet.

Thanks for the confirmation. I already knew this, but was looking for confirmation that Fiat has to force you in for unnecessary service intervals (to maintain your 4 year bumber/bumper warranty) and to make their money back on service fees they would otherwise lose since from my understanding EV's have virtually no maintenance costs vs an ICE.

I find it disappointing Fiat's service interval requires you get your brake linings etc. checked every 2 years for no reason. If regen. braking makes them last longer, why do I need to pay a service tech every two years unnecessarily to check them????

Hmm, I though the 500e had larger brakes than the standard cars? :confused:

Looks like there are some differences, however it also looks like Fiat messed up on printing the specs. I was told and in the press kit it states the front rotor size is the same as the Abarth (11.1) , but you'll see the specs say "11.0", plus they converted inches to mm incorrectly. I'll give them a heads up on that:


500e BRAKES
Availability: Standard on 500e
Front
Rotor size and type: 11.0 x 0.87 (284 x 22) vented with regenerative braking
Caliper size and type: 2.13 (54) single-piston with aluminum housing
Swept area: 218 sq. in (1410 sq. cm)
Rear
Rotor size and type: 9.4 x 0.4 (251 x 11) solid with regenerative braking
Caliper size and type: 1.50 (38) single-piston with aluminum housing
Swept area: 162 sq. in (1048 sq. cm)


STANDARD 500 BRAKES
Availability: Standard — 500 and 500c Pop and Lounge, 500 Sport
Front
Rotor size and type: 10.1 x 0.86 (257 x 22) vented
Caliper size and type: 2.12 (54) single-piston with aluminum housing
Swept area: 193 sq. in. (1,244 sq. cm)
Rear
Rotor size and type: 9.4 x 0.4 (240 x 11) solid
Caliper size and type: 1.33 (34) single-piston with aluminum housing
Swept area: 153 sq. in. (984 sq. cm)


ABARTH BRAKES
Availability: Standard — 500 Turbo and Abarth
Front
Rotor size and type: 11.1 x 0.86 (282 x 22) vented
Caliper size and type: 2.12 (54) single-piston with aluminum housing
Swept area: 193 sq. in. (1,244 sq. cm)
Rear
Rotor size and type: 9.4 x 0.4 (240 x 11) solid

Also, according to a US Law, you do NOT have to have maintenance work done at a dealer to maintain the warranty. Just maintain documentation that any maintenance was done. In other words, FIAT is not holding anyone hostage for maintenance with a recommended 2 year check on brakes.

I'm also going to guess this - every 2 years sounds like a fluid flush and that's gonna be pretty much the same for all cars. Due to regen, I would guess brake pad wear wouldn't be significant in 2 years.. the gas powered rentals from enterprise (near my studio) were doing a hard life and the folks told me the brakes looked new at pretty high miles..

Correct!

I would think with regenerative brakes and the assumed conservative driving nature of EV/hybrid drivers, the brake pads should last a very long time. My 01 VW Golf TDI would normally need the rear OEM pads changed every 40K miles or so, while the front pads lasted me 250K miles. I ended up switched the rear pads to Akebono ceramic pads and they've since gone 120K miles and look about 50% at this point. We also have an 07 Lexus Rx400h with 170K miles on the original rotors and pads.

The one thing I would caution everyone is with the brake fluid bleeding. It might require a special interface. On our Lexus, the only way to do the brake flush properly is through Toyota's propriety software, Techstream (though there are bootlegged versions all over the internet); this is because the brake actuator is electronically controlled so that it can function without a brake booster or vacuum when the ICE is not running. I assume the 500e has something similar. The TDI has requires VAG-COM to properly bleed the brakes in order to circulate the fluid out of the ABS pump. With the near zero maintenance cost of the 500e, I don't mind throwing a little money towards the Fiat dealership every 2 years for a brake fluid flush.

When I returned my 2013 at the end of the lease with 30k miles the brake pads still looked full thickness!
