Parts for your 2020 Mazda 3-Brake shoes

2020 Mazda 3 brake-shoes — what’s actually fitted

For the 2020 Mazda 3 (BP series), brake-shoes aren’t used. This model runs disc brakes front and rear with a caliper‑integrated Electric Parking Brake (EPB), so there’s no drum‑in‑hat setup and no separate brake-shoes anywhere on the car.

Tech sources back this up. The Mazda3 (BP) Workshop Manual outlines four‑wheel disc brakes and an EPB that uses an electric motor on the rear calipers rather than a drum and shoe arrangement. The 2020 Owner’s Manual covers EPB operation and servicing cautions but doesn’t list parking brake-shoes as service items. Mazda’s Electronic Parts Catalogue for the BP platform shows rear rotors, pads, calipers, and associated hardware — but no drums or shoes.

Why doesn’t it use brake-shoes? The BP‑series Mazda 3 was engineered around modern disc braking. Discs provide consistent stopping power, better heat management, and a more compact package alongside driver‑assist tech. The EPB is built into the rear calipers, which keeps weight down and integrates neatly with stability control and auto‑hold. Because the parking brake clamps the rear pads onto the rotors via the EPB motors, there’s simply no need for a secondary drum with shoes.

What should owners focus on instead of brake-shoes? Routine disc brake care. That means keeping an eye on pad thickness, rotor condition, and the EPB service procedure:

• Pad checks and replacement: Replace when friction material approaches about 3 mm, or earlier if there’s noise or glazing.
• Rotor health: Machine or replace if there’s vibration, scoring, or the rotor measures below the stamped minimum thickness.
• EPB service mode: Always place the EPB in maintenance/service mode before retracting rear caliper pistons or changing pads. Forcing pistons back without this can damage the EPB motors.
• Brake fluid: Refresh every two years regardless of kilometres to maintain a firm pedal and protect internal components.
• Cleaning and lubrication: Keep slide pins free and lightly lubricated with the correct high‑temp brake grease, avoid contaminating pad surfaces.

Bottom line: for a 2020 Mazda 3, a listing for “brake-shoes” isn’t applicable. The right parts are brake pads and rotors, and the key procedure is using the EPB service mode when doing rear brake work.

FAQs

Does a 2020 Mazda 3 have brake-shoes?
No. It has disc brakes front and rear with an Electric Parking Brake integrated into the rear calipers, so there are no drum brake-shoes on this model.

What should be serviced instead of brake-shoes on a 2020 Mazda 3?
Focus on brake pads, rotors, and correct EPB procedures. Check pad thickness, measure rotors against the minimum spec, change brake fluid every two years, and always use EPB service mode before retracting rear pistons.

How do you know the rear brakes need attention on a 2020 Mazda 3?
Listen for squeals or scraping, feel for pulsation under braking, and check the dash for EPB warnings. Visible pad wear (around 3 mm or less), scoring on rotors, or uneven pad contact are all signs it’s time for a proper brake inspection.
