  Q: How to Address Issues with the Clutch Master Cylinder in a Ford F-150?

  A:

  You should begin clutch master cylinder maintenance by removing all tubing from the automobile for bench bleeding operations. The first step involves disconnecting the push rod from the clutch master cylinder and clutch and brake pedal pivot shaft lever as well as the Clutch Pedal Position Switch (CPP). First disconnect the pushpins then disable the power supply to the air suspension system to avoid shifting during hoisting, jacking or towing. Vehicle hoisting should begin after you support it from beneath and detach the clutch hydraulic line that connects the slave cylinder and proceed with vehicle lowering. Turn the clutch master cylinder reservoir along with the clutch master cylinder 45 degrees clockwise to remove them. The rubber components must be cleaned with Ford High Performance DOT 3 Motor Vehicle Brake Fluid C6AZ-19542-AB either alone or with an equivalent DOT 3 product that satisfies the Ford specification ESA-M6C25-A. Next the clutch master cylinder should be thoroughly inspected for weak springs, damaged reservoir components, damaged cups and scored Pistons. Before installation position the clutch master cylinder reservoir inside a vise clamp before filling it with the original brake fluid up to the indicator line. The tube end facing the Clutch Slave Cylinder should direct flow to a waste container while keeping the reservoir liquid level constant to avoid system intrusion of air. The clutch master cylinder bleeding process should continue until strong brake fluid flow appears from the tube's quick connect coupling end. After this point use the male quick connect to open its internal parts while maintaining complete depression of the clutch master cylinder push rod. First release both the quick connect internal mechanism along with the clutch master cylinder push rod. Every step follows: The clutch master cylinder must rotate 45 degrees counterclockwise before installing pushpins and reattaching the clutch pedal position switch and connecting the clutch master cylinder push rod with its retainer bushing. Turn off any air suspension system electrical power before you raise and support the vehicle. After connecting the clutch hydraulic line to the transmission you should lower the vehicle then enable the air suspension switch (if equipped) before completing the clutch hydraulic system bleeding process.

  Q: How to service and repair the clutch master cylinder on Ford F-150?

  A:

  A technician should remove vehicle tubing before starting the bench bleeding process for clutch master cylinder service and repair work. First disconnect the clutch master cylinder push rod from the clutch and brake pedal pivot shaft lever and then disconnect Clutch Pedal Position Switch (CPP). The vehicle's air suspension system power should be turned off via the RH kick panel area before removing pushpins to protect it from shifting throughout the operation. First raise and support the vehicle and disconnect the clutch hydraulic line at the slave cylinder and lower the vehicle. The clutch master cylinder reservoir along with the clutch master cylinder should be removed by rotating it 45° clockwise. All rubber components within the clutch master cylinder require cleaning with Ford High Performance DOT 3 Motor Vehicle Brake Fluid or a DOT 3 equivalent that meets Ford specification ESA-M6C25-A while you inspect for a weak spring and check for reservoir component damage and cup damage and Piston scoring. Begin installation of the clutch master cylinder reservoir by placing it gently in a vise before filling it up to the mark with brake fluid matching the original type. Place the Clutch Slave Cylinder end of the tube into a waste container while keeping the reservoir at full level to shield against clutch master cylinder air contamination during bleeding. Bleed the clutch master cylinder until consistently strong brake fluid flow appears at the quick connect coupling end of the tube before opening the internal mechanism of the male quick connect coupling and fully compressing the clutch master cylinder push rod. Freeing both the quick end connector mechanism and the clutch master cylinder push rod enables the bleeding process. After installing the clutch master cylinder at a 45° counter-clockwise rotation you must secure its pushpins and attach both clutch pedal position switch components as well as the clutch master cylinder push rod and retainer bushing. Discontinue power to the air suspension system before performing the lifting and supporting process for the vehicle. After setting up the transmission connection of the clutch hydraulic line you should lower the vehicle and activate the air suspension switch when available before performing a clutch hydraulic system bleed procedure.
