Baer Brakes 14″ Extreme+ Rear Disc Brake Kit 4262339B — 6S Monoblock 6-Piston for 1994–2004 Ford Mustang SN95

Dominate the track and the street with Baer’s flagship rear brake system. The Baer disc brake kit 4262339B is a 14-inch Extreme+ rear brake system engineered specifically for the 1994–2004 Ford Mustang SN95 with the factory 8.8-inch solid rear axle. This is not a mild upgrade — it is a complete transformation. At the heart of this system sits Baer’s forged 6S Monoblock six-piston caliper, CNC machined in Phoenix, Arizona from US-sourced 2618 aluminum, clamping a massive 14-inch two-piece slotted, drilled, and zinc-plated rotor. If you are building a Pro Touring SN95, a road-course warrior, or a high-horsepower street machine, this Baer disc brake kit delivers the fade resistance, pedal modulation, and outright stopping power that factory brakes simply cannot match.

Why Choose the Baer Extreme+ Rear Disc Brake Kit?

Baer Brakes has been pushing the boundaries of performance brake technology for over 30 years. cite🛠web_search:39#14:~:text=For over 30 years Baer, Inc. has been pushing the boundaries of modern performance brake technology Every Extreme+ system is designed, machined, assembled, and powder-coated in Baer’s Phoenix, Arizona facility using materials sourced entirely from the USA. cite🛠web_search:39#14:~:text=All of Baer’s products feature material sourced from the USA…machined in house and the fit and finish of our products are completed in our warehouse as well, all in Phoenix, AZ

Key Features & Benefits

6S Monoblock Six-Piston Caliper: The 6S is a one-piece Monoblock caliper fully CNC machined from a US-sourced 2618 aluminum forging. The Monoblock design eliminates the caliper bridge flex common in bolt-together two-piece calipers, ensuring that more hydraulic pressure is applied to the pads rather than wasted caliper deflection. cite🛠web_search:39#0:~:text=1-piece Monoblock 6-piston, 6S caliper mounted to a 14″, 2 piece slot only rotor…fully machined in Phoenix, AZ from a US sourced 2618 Aluminum forging Six staggered pistons distribute clamping force evenly across the pad surface for superior modulation, reduced pad taper wear, and consistent bite lap after lap.

Stainless Steel Pistons & Abutments: The 6S caliper features stainless steel pistons and abutments that resist heat transfer into the brake fluid, reducing fade during repeated hard stops. D.O.T. compliant dust and weather seals ensure long-term durability in daily-driven and all-weather applications.

14-Inch Two-Piece Slotted, Drilled & Zinc-Plated Rotors: The massive 14-inch diameter rotor provides greater leverage and thermal mass than factory 11–12-inch SN95 rear discs. The two-piece design uses a billet aluminum hat bolted to the cast-iron friction ring with NAS high-grade stainless hardware, allowing the rotor to expand and contract freely under extreme heat without warping. cite🛠web_search:39#0:~:text=Rotors are pre-assembled with NAS high grade stainless hardware Slotted grooves evacuate gases and debris, drilled holes improve wet-weather bite, and the zinc plating resists corrosion for a lasting show-quality finish behind open wheels.

Integrated Modern Parking Brake: Baer’s unique backing plate not only acts as a caliper mount but also houses a modern one-piece parking brake shoe assembly. cite🛠web_search:39#0:~:text=Baer’s unique backing plate not only acts as a caliper mount, but also houses a modern 1-piece park brake shoe assembly This is a critical feature for street-driven builds — you retain full parking brake functionality without the bulk and unreliability of factory drum-in-hat designs.

Stainless Braided Brake Hoses & Hardware: The kit includes stainless braided flex hoses and all necessary mounting hardware. Braided lines resist expansion under pressure, delivering a firmer, more responsive pedal feel compared to factory rubber hoses.

D1247 Pad Compound: The 6S caliper uses the popular D1247 pad type, widely available in street, performance, and race compounds. Swap pads to match your driving style without changing calipers. cite🛠web_search:39#0:~:text=uses the popular D1247 pad type

18-Inch Minimum Wheel Requirement: The 14-inch rotor and six-piston caliper require a minimum 18-inch wheel diameter. Baer recommends verifying fitment using template N135P before ordering, as wheel spoke design and barrel shape vary by manufacturer. cite🛠web_search:39#0:~:text=The 14″ Extreme+ fits most 18″ or larger wheels

Vehicle Fitment

This Baer disc brake kit is specifically engineered for the following applications:

Primary Fitment:

• 1994–2004 Ford Mustang (SN95 platform) — all models with the factory Ford 8.8-inch solid rear axle (C-clip design)

Additional Fitment:

• 1993 Ford Mustang Cobra — when equipped with a 5-lug axle swap

Important Fitment Notes:

• Solid axle only. This kit does NOT fit SN95 Mustangs with the Independent Rear Suspension (IRS) — verify your rear axle type before ordering. cite🛠web_search:39#0:~:text=Fits 94-04 Mustang OE 8.8″ C-clip solid rear axle w/3.250″ Standoff (Does NOT fit IRS)
• Requires a 5×4.50-inch (5×114.3 mm) wheel bolt pattern — standard for SN95 Mustangs.
• Requires 18-inch or larger wheels with adequate barrel clearance for the 14-inch rotor and 6S caliper.
• 3.250-inch standoff dimension — confirm your axle housing matches factory SN95 8.8-inch solid axle specifications.

Because of the abundance of wheel companies and styles, it is impossible for Baer to guarantee fit of their brake systems into a specific wheel style and/or manufacturer. To verify fitment, we recommend using template N135P specific to this system and comparing it to the wheel of choice. cite🛠web_search:39#0:~:text=Because of the abundance of wheel companies and styles, it is impossible for Baer to guarantee fit of their brake systems into a specific wheel style and/or manufacturer

Technical Specifications

Installation Overview

The Baer disc brake kit 4262339B is designed as a direct bolt-on replacement for factory rear drum or disc brakes on SN95 Mustangs with the 8.8-inch solid axle. The kit reuses factory axle housing mounting points and includes all brackets, hardware, and lines necessary for installation. However, professional installation by a qualified brake technician is strongly recommended.

General Installation Steps:

1. Secure the vehicle on quality jack stands and remove the rear wheels.
2. Remove factory rear brakes — drums, calipers, rotors, backing plates, and parking brake hardware.
3. Clean the axle flange and verify the 5×4.50 bolt pattern and 3.250-inch standoff dimension.
4. Install the Baer backing plate/caliper mount assembly onto the axle housing using supplied hardware.
5. Mount the two-piece rotor onto the axle hub. Verify smooth rotation and proper lateral runout.
6. Install the 6S Monoblock caliper with pads onto the rotor and torque all fasteners to Baer’s specifications.
7. Connect stainless braided brake hoses to the hard line junction. Ensure no rubbing at full suspension travel.
8. Adjust and connect the integrated parking brake cable to the factory or aftermarket parking brake lever.
9. Bleed the rear brake circuit thoroughly using fresh DOT 3 or DOT 4 brake fluid.
10. Bed-in the pads and rotors per Baer’s recommended procedure before aggressive driving.

Note: A properly sized master cylinder and adjustable proportioning valve are recommended when upgrading to four-wheel disc brakes, especially if the front brakes have also been upgraded. Contact our technical team for brake bias recommendations.

Brake Bias & System Matching

Installing a high-performance rear Baer disc brake kit without addressing the front brakes and hydraulic balance can lead to unpredictable handling under hard braking. For optimal performance and safety, we recommend pairing the 4262339B rear kit with:

Baer Extreme+ Front Brake Kit: Match your rear 14-inch Extreme+ system with an equivalent Baer front kit for balanced braking performance and consistent pedal feel front to rear.

Adjustable Proportioning Valve: Fine-tune front-to-rear brake pressure to prevent rear lockup during threshold braking. Essential when mixing factory front brakes with upgraded rear discs.

Master Cylinder Upgrade: Factory SN95 master cylinders may not provide adequate fluid volume for large-bore six-piston calipers. A Baer Remaster or equivalent 1-inch bore dual-reservoir master cylinder ensures proper pedal firmness and stroke.

High-Performance Brake Fluid: DOT 4 or DOT 5.1 fluid with high dry and wet boiling points to resist fade during track days and aggressive street driving.

Baer Claw Brake Pads: Replacement D1247 pads available in street, performance, and track compounds to match your driving style.
