For 2015 and earlier models, initially release the plastic tab above the clutch pedal; thereafter suck out the hydraulic fluid from the brake master cylinder reservoir using a syringe. Expect to cover fluid fittings with rags and caps to avoid drips, this can harm paint work, especially brake fluid. Remove the nut on the negative battery terminal, take out the battery together with the tray and shift the place of the coolant expansion tank but do not detach any hose. Bend the hydraulic line and remove the securing clip and unclamp it and remove the hydraulic line from the clutch master cylinder and the fluid feed hose. To do so, use special pliers to disconnect the master cylinder pushrod from the clutch pedal , and then unbolt the clutch master cylinder from the firewall. For installation, feed the pushrod through the firewall, and tighten the numerate mounting nuts and the pushrod is to be locked into the pedal retainer. Join the hydraulic line fitting and the fluid feed hose, then the coolant expansion tank, the battery tray and battery, refill the brake fluid and service the clutch hydraulic system. Feel the brake pedal and perform the brake hydraulic system bleeding where required. On 2016 and later models, the process begins with the removal of the cowl panel and the negative battery cable. Remove the coolant expansion tank and remove the electrical connections of the brake master cylinder. Pump and drain the brake master cylinder reservoir, disconnect the hydraulic line leading form the clutch master cylinder, and pull out the brake master cylinder. You have to take off the ABS ECU/hydraulic unit mounting bolt, release the brake lines clips and rear the hydraulic unit. Loosen the clutch release/actuator cylinder line and then push the brake booster as far as possible to have access to the nuts of the pedal assembly. Interior wise, the project involves dismantling the steering column covers, driver's side floor air duct, and steering column. The accelerator pedal position sensor is to be as well as the clutch pedal position sensor detached for now, but their positions would have to be noted for later replacement. Take out the guide element and the bolts for the mounting of the pedals, then Indian the wiring harness in addition to the removal of brake pedal push rod. Detach the pedals, be very careful in this process so as not to spill brake fluid. To do this, you require special pliers to remove the clutch master pushrod from the pedal and further turn and pull the clutch master cylinder. To assemble the unit, mount the master cylinder over the pedal assembly by a means of a lock, and then fit the pushrod to the clutch pedal. Place the guide element on the firewall stud, put the rest of the pedal assembly in, and fasten it. Finally secure the mounting bolts and finish the process by undoing the procedures described in this step but remember to bleed the brake and clutch hydraulic system.
