HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE

HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE

The HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE is identified as a dedicated replacement rear brake rotor for Honda CBR 250 and CBR 150 motorcycles. The rear disc rotor serves as the critical friction surface against which the rear caliper brake pads clamp during hydraulic braking. Matching the exact mechanical mounting dimensions of the wheel hub is essential to maintain safe, predictable braking performance.

Technical Overview & Identification

When ordering a replacement HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE, verify the specific motorcycle generation, model year, and fitted hub assembly. Some motorcycle editions use alternative wheel castings or aftermarket hubs that differ from factory specifications.

• Vehicle Application: Honda CBR 250 and CBR 150 two-wheelers (confirm year and wheel configuration).
• Mounting Location: Rear wheel position only; not suitable for front brake hubs.
• Part Category: Solid motorcycle disc brake rotor plate. Caliper and mounting fasteners sold separately.
• Supplied Quantity: One individual rear brake disc plate.
• Verification Status: Material metallurgy, surface finish, and warranty terms are determined by batch availability.

Rotor Dimensions & Measurement Guide

Before fitting a new HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE, dismount the worn disc and verify five essential dimensional checks using a digital vernier caliper and micrometer:

• Outer Diameter (OD): Measure across the outer braking track to verify total swept area compatibility.
• Center Bore Diameter (ID): Check the central locating hub hole to ensure a snug centering fit without radial play.
• Bolt Pitch Circle Diameter (PCD): Measure the exact distance between diagonally opposite mounting bolt holes.
• Bolt Hole Count & Diameter: Confirm the number of countersunk or stepped bolt apertures.
• Rotor Thickness & Minimum Discard Limit: Measure nominal thickness and compare against the service wear limit stamped on your original rotor.

Compatibility & Wheel-Side Verification

The HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE must sit perfectly flush against the rear wheel hub mating face. Thoroughly inspect the hub face for burrs, grime, rust, or metal shavings before disc placement. Even microscopic debris trapped between the rotor and wheel hub causes axial runout, leading to noticeable brake lever pulsation and uneven pad wear.

Verify that the rear brake caliper bracket, axle spacers, and swingarm alignment marks are positioned accurately. The caliper carrier must hold the brake pads centered evenly over the disc rotor swept track. If the wheel was previously converted or modified, factory part lookups may not match your physical setup.

Workshop Torque Specs & Installation

Proper mechanical installation ensures reliability and rider safety. Follow standard workshop procedures when securing your HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE:

• Fastener Preparation: Clean the hub threads thoroughly using brake cleaner and compressed air. Apply a drop of medium-strength thread locker to each disc bolt.
• Tightening Sequence: Fasten the bolts finger-tight, then tighten them progressively in a diagonal star or criss-cross pattern to distribute clamping pressure evenly.
• Torque Specification: Use a calibrated torque wrench according to service manual guidelines (typically 20–24 Nm for M8 disc bolts). Do not overtighten or use pneumatic impact guns.
• Runout Inspection: Mount a dial indicator gauge on the swingarm with the probe contacting the outer braking surface. Spin the wheel by hand; lateral runout should remain within acceptable workshop limits (under 0.10 mm).

Hydraulic Bleeding & Bedding-In Procedure

Whenever replacing a rear disc rotor, inspect the condition of the rear brake pads, caliper slider pins, and hydraulic fluid. Installing worn, glazed, or tapered brake pads onto a brand-new disc will score the metal track prematurely and reduce stopping power. Install fresh compatible brake pads for optimum friction contact.

Inspect brake fluid color in the rear master cylinder reservoir. Flush with fresh DOT 3 or DOT 4 fluid if old fluid appears dark or contaminated. Bleed the hydraulic circuit to eliminate trapped air bubbles and confirm a firm pedal stroke before test riding.

Execute a gentle bedding-in cycle during the first 100 kilometers. Perform moderate stops from medium speeds without locking the rear wheel, allowing the friction material to transfer evenly onto the rotor face without thermal shock.

Common questions about HONDA CBR 250 CBR 150 REAR DISC BRAKE PLATE

Q: Is this rear disc compatible with all Honda CBR 250 and CBR 150 editions?
A: No. Confirm your wheel hub, production generation, bolt pattern, and original rotor dimensions before ordering.

Q: What measurements should be checked against the removed rotor?
A: Measure the outer diameter, central locating hole, bolt circle diameter, thickness, and mounting offset.

Q: Are mounting bolts or rear brake pads included with the plate?
A: The listing identifies a single disc plate. Caliper units, mounting bolts, and pads are separate items.

Q: Is the product image an actual photograph of the rotor?
A: No. It is an original labeled title card displayed while verified warehouse photography remains pending.

Q: What is the recommended running-in procedure after replacement?
A: Avoid aggressive hard braking for the first 100 km to allow smooth, even friction transfer between pads and disc.
