TRQ Rear Brake Caliper Set Compatible with 2004-2008 Mazda 3 - Direct

In this review of the TRQ Rear Brake Caliper Set for the 2004-2008 Mazda 3, the bottom line is simple: this kit is for owners who need a complete, ready-to-install rear caliper replacement with minimal fuss. The reviewer found the set to be a straightforward direct replacement that restores braking function without modification, and appreciates that both driver and passenger calipers, brackets and hardware are included so a single purchase completes the repair. Fit and initial performance meet expectations for an aftermarket OE replacement.

Key Features

• Complete 2-piece kit: Includes rear driver and passenger calipers with brackets and hardware so both sides can be serviced at once.
• Direct replacement fit: Designed to mount without modifications, saving time and avoiding unexpected parts swaps during installation.
• Durable protection: Zinc coated components give added corrosion resistance for longer life in wet or salted roads.
• Upgraded seals: EPDM seals improve resistance to thermal deterioration compared with older-style seals.
• No core charge: All calipers are new assemblies, so there is no need to return old cores or worry about extra fees.

Who It's For

The TRQ rear caliper set is best for Mazda 3 owners with the L4 2.3L engine from 2004 through 2008 who want a complete rear caliper replacement that includes brackets and the abutment kit. It suits DIYers and independent shops that prefer to replace both rear calipers at once to ensure matched performance and to avoid repeat labor.

Those who should look elsewhere include drivers needing calipers for other Mazda models or years, or technicians seeking OEM-branded parts; this is a quality aftermarket OE replacement rather than an original equipment part. If you need calipers with integrated parking brake actuators or different fittings, confirm fitment before buying.

Pros & Cons

• Good overall fit and functionality with included mounting brackets and hardware for a one-stop repair.
• Quality construction and finish noted by users, including a pleasing appearance and no core charge.
• EPDM seals and zinc coating contribute to resistance against thermal wear and corrosion.

Cons

• Corrosion resistance received mixed feedback from customers, so longevity may depend on local road conditions and maintenance.
