Front Brake Caliper Bracket 8-98078168-1 8980781680 For ISUZU D-MAX 12 (2012+) 4x2 — Floating Caliper Support Bracket, OEM-Spec Aftermarket, 6-Month Warranty

The Front Brake Caliper Bracket with OEM references 8-98078168-1 / 8980781680 is a verified replacement brake component for the ISUZU D-MAX 12 (2012+ generation) 4x2 (rear-wheel drive) pickup platform, equipped with 4J-series diesel engines. This bracket is the stationary mounting support for the front brake caliper — the critical structural link that rigidly connects the caliper to the front axle spindle, providing the fixed reference point against which the floating caliper slides during braking.

In a floating caliper system, the bracket does not move. It is bolted rigidly to the axle (spindle) and carries the guide pins on which the caliper housing slides. When hydraulic pressure is applied, the caliper housing moves along these guide pins, clamping the brake pads against both sides of the rotor. The bracket therefore determines caliper alignment, pad wear geometry, and braking stability. A bent, cracked, or corroded bracket can cause uneven pad wear, brake drag, or reduced braking force on one side.

The bracket is supplied as an OEM-specification aftermarket component manufactured in China, with a reference actual size of 22.8 × 9.5 × 8 cm, a 6-month quality guarantee, and a 3-month warranty reference from one aftermarket supplier. The ISUZU factory description is "SUPPORT; FRT DI" (Support; Front Disc).

• Position & System Verified: Front brake caliper support for a floating caliper system — confirmed by Polish, Russian, German, and Dutch supplier catalogs describing the bracket's function as securing the stationary portion of the caliper and providing a rigid reference point on the axle (spindle).
• Vehicle & Drive-Type Coverage Verified: ISUZU DMAX12 4X2 — confirmed across Persian, Hindi, Russian, German, Dutch, Italian, and Polish supplier portals.
• OEM Factory Description Verified: "SUPPORT; FRT DI" — confirmed by Ecer / Yimi (Guangzhou) factory data and dts.lv OEM parts catalog.
• Dimensions Verified: Actual size 22.8 × 9.5 × 8 cm — confirmed by Ecer / Yimi factory data (Russian and other language portals).
• Warranty Reference: 6-month quality guarantee (Ecer / Yimi factory) and 3-month warranty (Persian supplier) — confirm tier at inquiry.
• Cross-Reference / Platform Overlap Verified: 8-98078-168-0 is confirmed by Euro4x4parts as the front caliper support for D-MAX 1 (8DH) 2008/07 – 2012/05, indicating that the same bracket family serves both late D-MAX 1 and D-MAX 12 applications in some configurations. 8-98049-958-0 / 8-97328-493-0 is the earlier D-MAX 1 bracket (2006/10 – 2008/06) — a different reference, not interchangeable.

• Uneven or accelerated brake pad wear: A bent or corroded bracket prevents the caliper from sliding squarely, causing one pad to wear faster than the other or the pads to wear at an angle.
• Brake drag / overheating wheel: A bracket that has lost alignment or has corroded guide pin bores keeps the caliper from releasing fully, producing drag, heat, and a burning smell.
• Vehicle pulls to one side during braking: A misaligned bracket on one side applies uneven clamping force, causing the vehicle to pull toward the affected side.
• Clunking or knocking from the front brake area: A loose or cracked bracket allows the caliper to shift under braking load, producing a metallic clunk.
• Visible cracks, deformation, or severe corrosion on the bracket body: Impact damage or corrosion thinning of the bracket compromises its structural rigidity and caliper alignment.
• Guide pin bore wear or elongation: Worn guide pin bores in the bracket allow the caliper to cock and bind, leading to uneven pad wear and poor brake feel.

• 4x2 vs. 4x4 is the first check: This bracket is confirmed for DMAX12 4x2 (two-wheel drive). The 4x4 (four-wheel drive) variant may use a different caliper bracket due to different front suspension and steering knuckle geometry. Confirm the vehicle's drive type and VIN before ordering.
• D-MAX 12 vs. D-MAX 1 platform boundary: The 8-98078-168-0 reference is confirmed for both late D-MAX 1 (2008/07 – 2012/05) and D-MAX 12 (2012+) in different catalogs. However, production changes across the platform transition may affect bracket dimensions or guide pin placement. Physically compare the replacement against the original bracket — do not rely solely on the OE number when crossing the D-MAX 1 / D-MAX 12 boundary.
• Left vs. Right: Euro4x4parts lists the 8-98078-168-0 support as "Front Left or right side" — suggesting the same bracket may serve both sides on the D-MAX 1 platform. However, for D-MAX 12, the Persian supplier lists it as a front bracket without specifying left/right. Confirm whether the bracket is handed (left/right specific) or universal for your specific vehicle before ordering.
• Bracket only — caliper, pads, and guide pins are separate: This is the bracket/support only. The caliper housing, brake pads, guide pins, and mounting bolts are not included unless explicitly stated.

1. Confirm the required part first: Verify that the original bracket is the front caliper support and that the vehicle is a 4x2 D-MAX 12. Compare the guide pin bore layout and mounting hole spacing to the replacement.
2. Safety first: Park on level ground, engage the parking brake, and chock the rear wheels. Loosen the front wheel lug nuts before raising the vehicle. Support the front corner securely on jack stands.
3. Remove the caliper: Unbolt the caliper guide pins (or slide pins) from the bracket. Support the caliper to avoid stressing the brake hose — do not let it hang by the hose.
4. Remove the old bracket: Unbolt the bracket from the steering knuckle / axle spindle. Note the orientation and any shims or spacers.
5. Clean the mounting surfaces: Remove all dirt, rust, and old thread-locking compound from the knuckle and bracket mating surfaces. A clean, flat surface is essential for correct caliper alignment.
6. Install the new bracket: Position the 8-98078168-1 bracket onto the knuckle. Install the mounting bolts and torque to the workshop manual specification. Do not over-torque — the bracket or knuckle can distort.
7. Lubricate and install guide pins: Apply high-temperature brake grease to the guide pins and insert them into the bracket bores. Do not use ordinary chassis grease — it will degrade at brake temperatures.
8. Reinstall the caliper: Slide the caliper housing onto the guide pins and secure the retaining bolts. Verify that the caliper slides freely on the pins through its full range of motion.
9. Bleed the brake system (if the hose was disconnected): Bleed the front circuit until clear, bubble-free fluid flows.
10. Test operation: Pump the brake pedal to seat the pads. Check for brake drag by spinning the wheel by hand — it should rotate freely. Road-test at low speed, checking for even braking and no pull.

• Inspect the bracket and guide pins at every brake pad replacement or every 20,000 – 30,000 km — check for corrosion in the guide pin bores and wear on the pins.
• Lubricate the guide pins with high-temperature brake grease at every pad service.
• Replace the bracket if the guide pin bores are elongated, the bracket is cracked or bent, or severe corrosion has thinned the structure.
• Use new guide pins and boots when installing a new bracket if the originals show any wear or corrosion — reusing worn pins in a new bracket accelerates bore wear.

• Standard packing: Neutral carton with protective wrapping; customer-branded packaging available on request.
• Package contents: 1 × Front Brake Caliper Bracket (Support). Guide pins, boots, mounting bolts, caliper, and brake pads are not included unless explicitly stated — confirm exact package contents at inquiry.
• Set options: Single bracket / left + right pair (if handed — confirm applicability) — specify at inquiry.
