Big Brake Kit for INEOS Grenadier FRONT brakes by Alcon & Agile Offroad

Installation Manual

Developed by Alcon and engineered for the INEOS Grenadier, this front brake kit is built to withstand the demands of heavy off-road use while improving on-road safety and control. The upgrade replaces the factory 12-5/8” rotor and 2-piston cast-iron caliper with a massive 13.5” diameter rotor and robust 4-piston cast iron caliper. A billet steel, zinc-plated caliper bracket ensures precise mounting and long-term strength. The kit also includes corrosion-treated rotors with directional cooling vanes for better heat management and a set of braided steel brake lines to complete installation. Designed to clear factory wheels as well as Agile’s Overland HD and XT wheels, this system offers uncompromising performance without sacrificing fitment.

Installation Steps

1

Remove both driver and passenger side wheels.


2

Use a T25 Torx bit to remove the two brake line bracket screws.


3

Unclip the wheel speed sensor harness from the three brake line clips and the brake line bracket.


4

Use a 21mm socket to remove the two caliper bolts.


5

Hang the caliper forward of the axle using a caliper hanger hook.


6

Use a T45 Torx bit to remove the rotor retaining screw. Remove factory rotor. Use a rubber mallet to remove rotor if necessary.


7

Clean hub using a wire brush and brake parts cleaner if necessary.


8

Install one of the supplied caliper brackets using the factory caliper bolts.


9

Apply a few drops of blue threadlocker and then torque to 120 ft lbs.


10

Install the supplied rotor using the factory retaining screw. Make sure new rotor is completely seated on hub. Torque screw to 18 ft lbs.

NOTE: Rotors are side specific. Refer to the part #.


11

Install supplied caliper using two of the supplied caliper bolts. Use a 10mm Allen wrench to fully tighten caliper bolts. Torque to 75 ft lbs.


12

Remove the caliper brake line port cap.


13

Install one of the supplied brake lines using two supplied copper washers and banjo bolt as shown.


14

Point the brake line up and then use a 14mm wrench to fully tighten banjo. Torque to 15 ft lbs.


15

Re-position the factory caliper to the rear side of axle. Re-install the brake line bracket using the factory screws.


16

Use an 11mm open wrench to remove the factory brake line from the factory caliper. Use a 14mm and a 17mm open wrench to separate the brake lines at the brake line bracket.


17

Use an 11mm open wrench and 17mm open wrench to install the new brake line to the brake line bracket. Clip in the wheel speed sensor to the factory brake line clips.


18

Repeat steps 2-17 to the opposite side.


1 Brake Pad Wear Sensor

The US model Grenadiers come equipped with a brake pad wear sensor located on the driver’s side caliper. The new Alcon calipers do not come equipped with a brake pad wear sensor. To avoid a brake sensor warning light, perform the following steps.

Locate the brake pad wear sensor harness going from the chassis bracket to the caliper. Unclip the harness from the five factory brake line clips.


2

Press and pull on the female brake pad wear sensor harness connector to disconnect from bracket. Use a clip removal tool to remove male sensor harness connector from bracket.


3

Press and pull on the female brake pad wear sensor harness connector to disconnect from caliper. Completely remove harness.


4

Use a 4mm Allen wrench to remove sensor connector from factory caliper.


5

Use a pair of wire cutters to remove the sensor connector from factory caliper.


6

  1. Remove the wire sleeve then trim and splice connector wires.
  2. Use a butt connector to join both wires.
  3. Shrink wrap butt connector.
  4. Remove metal bracket from connector.

7

Use a zip tie to attach modified connector to chassis bracket. Connect both brake pad wear sensor harness connectors together.


Bleeding Brake System

  • Bleed the brakes in accordance with the vehicle manufacturer’s instructions.
  • Only use DOT 4 brake fluid. The caliper bleed screws must be tightened to 18Nm (cold).
  • To prevent damage to any painted surface, remove any spilled brake fluid immediately with clean cold water.
  • Remove any fluid in the area around the bleed screw thread and in the end of each bleed screw.
  • Check the complete hydraulic system for leaks before driving the vehicle.
  • Make sure the brake system has been sufficiently bled and a firm brake pedal has been achieved.
