Front Brake Discs & Pads

Why Fiat 500 Discs and Pads Wear Out (and How Fast)

Here is the odd thing about braking on a Fiat 500: the discs usually die of rust, not wear. Most 500s live in town, cover low annual mileage and sit outside between short trips, so the discs never get hot enough for long enough to keep their faces clean. Surface corrosion pits the swept area, the pads then ride over a rough surface, and by MOT time the tester writes "discs pitted" on a car with barely 30,000 miles on it.

Pads on a 1.2 city car last roughly 25,000–35,000 miles of stop-start driving - the car is light, but town braking is constant. The small 240mm front discs are typically good for two pad sets by wear, though on a low-mileage 500 corrosion usually gets them first. If your discs have a deep lip or visible pitting, do discs and pads together as this guide shows rather than putting fresh pads on ruined faces.

Fiat Dealer vs DIY Cost

Typical UK prices for the front axle of a 2008-on Fiat 500. The 500's parts are among the cheapest of any modern car.

The saving is £140–£350 for a job with no special tooling and no electronics involved. See our UK brake replacement cost guide for how the 500 compares with other small cars.

Genuine Fiat Parts vs Aftermarket

Brembo - the brand people pay a premium for on performance cars - is Italian, and supplies a large share of Fiat's original brake components. A Brembo, Mintex or ATE disc and pad set at £60–£100 is the same quality that left the factory, without the genuine-parts markup of roughly double at the dealer counter. There is no braking argument for the Fiat-boxed part on a 500.

What to skip is the sub-£40 full axle set from an online marketplace. Soft castings warp, the friction material glazes on the first hard stop, and on a car this light you will actually feel cheap pads - the 500's pedal is honest and tells you everything.

Common Mistakes on a Fiat 500 Brake Job

• Fighting the disc retaining screw with a hand screwdriver. After a decade of British winters it will be seized. Use an impact driver from the start - rounding it off turns a two-hour job into a drilling session.
• Not cleaning the hub face. 500 hubs rust badly. Any crust left between hub and new disc creates run-out, and run-out becomes steering-wheel judder within a few thousand miles.
• Leaving the anti-corrosion coating on new discs. Most new discs arrive with an oily protective film. Brake cleaner on both faces before the wheel goes back on, or the first press of the pedal is a fright.
• Pushing the piston back with the reservoir full. The 500's reservoir is small and overflows easily - check the level before you clamp the piston home.
• Ignoring the caliper slides. The single-piston caliper depends on two greased pins to centre itself. Dry pins mean one pad does all the work and wears out in half the time.
• Skipping the bedding-in. Gentle braking for the first 150 miles. Hard stops on fresh discs and pads glaze the new friction surface permanently.

Related Faults to Check While the Front End Is Up

Fiat 500s of this age knock and rattle at the front, and with the wheel already off you can check the usual suspects in minutes: drop links (the classic 500 knock over speed bumps), lower wishbone bushes and the track rod ends. Grab the disc at top and bottom and rock it - play here is a wheel bearing or a worn ball joint. We cover both jobs step by step in the Fiat 500 lower wishbone guide and the Fiat 500 shock absorber guide.

Also flex the rubber brake hoses and look for cracking - they are original on most 500s of this age and cheap to do while the fluid system is already being disturbed. If you are chasing a specific noise rather than doing routine replacement, run it through the symptom finder first.
