Summary
Some 2021-2022 F-150 vehicles equipped with light duty electric park brake calipers (minor feature code FAJAK) may exhibit a squeal noise from the rear brakes after sitting for 8 hours or more. To confirm a vehicle is built with minor feature code FAJAK, review the build information by double-clicking the vehicle identification number in the upper left-hand corner in the Professional Technician System (PTS). To correct this condition, replace rear brake disc (ML1Z-2C026-C) and rear brake pads, caliper pin bolts, and brake pad holding clips (ML3Z-2200-E) on both sides of the vehicle. Refer to Workshop Manual Section 206-04 Rear Disc Brake. For claiming, use causal part number 2552 and applicable labor times from Section 02 of the Service Labor Times Standard Manual. NOTE: Using incorrect service parts on the braking system could impair brake performance.

It effectively solves the common bending/deformation issue of similar caliper spreader wrenches under heavy force. Professional caliper piston compressor/brake pad spreader for single, twin, and quad piston calipers
- 【How to Use the Brake Pad Spreader】This tool only works when the two iron sheets are squeezed, firmly grip the iron sheets and shake the handle up and down to understand how it works, adjust the middle switch for expansion or compression with an adjustable working range of 1.47–2.72 inches, then set the tool to the proper size, place it at the caliper piston and shake until the piston fully returns to its original position. Attention: remember to keep the tool centered while shaking and do not apply force unevenly to one side, as this may cause the iron sheets to bend due to unbalanced stress or damage the internal thread structure. We can offer replacements for any damaged parts
- 【Compared with the traditional C-shaped compression tool】This product utilizes the principle of leverage to save effort, and its larger contact area prevents it from slipping during the squeezing process. It can be used from multiple angles and is adaptable to complex automobile repair environments, and has two functions: compression and expansion
- 【Two hooks and two bottles of lubricating oil included】The hooks are used to hang your brake discs, preventing them from shaking when you repair the car alone. The two bottles of lubricating oil have the functions of preventing rust and abnormal noises. They should be applied to the back of the brake shoes. Please do not apply them to the contact surface of the brake pistons, as this may easily cause slipping
