Front Brake Caliper Support Bracket 8973017290 8-97301-729-0 For ISUZU D-MAX 1 (8DH) TFR54 4x2 (2003–2012) — OEM Genuine, Front Left Or Right, 24×9×8cm

The Front Brake Caliper Support Bracket with OEM reference 8973017290 / 8-97301-729-0 is a verified ISUZU Genuine brake component for the D-MAX 1 (8DH, 2003–2012) platform, specifically the TFR54 4x2 configuration within the 07/2003–09/2006 production window. ISUZU's official parts catalogue describes this bracket as "SUPPORT FRT DI" (Front Disc Support), confirming its function as the stationary mounting support for the front floating brake caliper.

In a floating caliper brake system, this bracket is bolted rigidly to the steering knuckle/axle spindle and carries the guide pins on which the caliper housing slides. When hydraulic pressure is applied, the caliper housing moves along these 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.

Euro4x4parts confirms this bracket is "Front — Left or right side" and corresponds to diagram part #32A for the D-MAX 1 (8DH) TFR54 4x2 2003–2006 application. The unit is supplied as ISUZU Genuine (reference price €256.67 TTC), described as "exactly the same as the one mounted at the factory." An aftermarket equivalent is also referenced under 8973017291 for the DMAX12 4x2 application, with actual dimensions 24 × 9 × 8 cm and a 6-month quality guarantee.

• Part Type Verified: "Brake caliper – support" — confirmed by Euro4x4parts; ISUZU factory description "SUPPORT FRT DI" — confirmed by Balleydier (official ISUZU dealer since 2010).
• Position Verified: Front — Left or right side — confirmed by Euro4x4parts ("Front Left or right side" / "Avant Côté gauche ou droit").
• Vehicle Coverage Verified: ISUZU D-MAX 1 (8DH) 2003–2012, V.U. TFR54 4x2 (general) 2003–2006 — confirmed by Euro4x4parts fitment data.
• Production Window Verified: 07/2003 – 09/2006 — confirmed by Euro4x4parts.
• OEM Genuine Status Verified: "pièce d'origine Isuzu", "exactement la même que celle montée à l'usine" — confirmed by Balleydier official ISUZU dealer.
• Dimensions Verified (aftermarket equivalent): 24 × 9 × 8 cm — confirmed by YIMI/Polish supplier data for the 8973017291 / 8-97301729-0 equivalent.
• Warranty Reference (aftermarket): 6 months — confirmed for the 8973017291 equivalent.
• Aftermarket Reference: 8973017291 (YIMI) is listed for DMAX12 4x2 with factory number 8-97301729-0 — providing a cross-reference lead, though platform generation must be confirmed.
• Net Weight: Not publicly disclosed. Confirm at inquiry for freight planning.

• 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 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 only: This bracket is confirmed for TFR54 4x2 (two-wheel drive). The 4x4 variant uses a different front suspension and steering knuckle geometry, and likely a different caliper bracket. Confirm the vehicle's drive type and VIN before ordering.
• Left or Right — but not handed: Euro4x4parts lists this bracket as "Front Left or right side," indicating the same bracket serves both sides on the D-MAX 1 TFR54 4x2 application. However, confirm against the original unit — production changes or market variants may introduce handedness.
• D-MAX 1 vs. D-MAX 12 boundary: The 8973017291 aftermarket reference is listed for DMAX12 4x2, while 8973017290 is confirmed for D-MAX 1 (8DH) TFR54 4x2. They share the same factory number (8-97301729-0), but the primary reference and platform generation differ. Physically compare the replacement against the original bracket — do not assume interchangeability across the D-MAX 1 / D-MAX 12 boundary without verification.
• Genuine vs. aftermarket: This bracket is available as ISUZU Genuine (reference price ~€256.67 TTC) and as an aftermarket equivalent (8973017291, ~6-month warranty). Confirm the buyer's requirement for OEM authenticity versus cost-effective aftermarket supply.

1. Confirm the required part first: Verify that the original bracket is the front caliper support and that the vehicle is a D-MAX 1 (8DH) TFR54 4x2 within the 07/2003–09/2006 window. 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 8973017290 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. Check for drag: With the wheel installed, spin the wheel by hand — it should rotate freely without brake drag. A dragging caliper indicates incorrect bracket alignment or seized guide pins.
10. Road test: Test drive at low speed, checking for even braking and no pull. Re-inspect the bracket bolts and guide pins after the first 500–1,000 km.

• 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 packing or customer-requested packaging; export pallet available for bulk orders.
• Package contents: 1 × Front Brake Caliper Support Bracket. 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 universal for the confirmed TFR54 4x2 application) — specify at inquiry if a pair is required.
• Suitable for: ISUZU D-MAX 1 brake system repair shops, pickup fleet maintenance departments, spare parts distributors, and export wholesalers serving Southeast Asia, the Middle East, Africa, and Latin America.
• Related parts available: Front brake caliper (different reference), brake pads, brake rotors, guide pin kits, caliper repair kits, and brake fluid for the D-MAX 1 platform.
