NHTSA ID Number: 10236024
Manufacturer Communication Number: SSM 51590
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.

- 【How to Use Brake Pad Spreader】This tool only works when the two iron sheets are tightened, firmly hold 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 1.7-6.8cm, then adjust the tool to the proper size, put it on the caliper piston and shake until the return piston and fully in its original position. Attention: remember to keep the tool centered while shaking and do not apply unevenly force on one side, as this may cause the iron sheets to bend due to unbalanced stress or damage to the internal thread structure. We can offer replacements for any damaged parts
- 【Compared to Traditional C-Shaped Compression Tool】This product uses the principle of leverage to save effort, and its larger contact area prevents it from slipping during the compression process. It can be used from multiple angles and is adaptable to complex car repair environments, and has two functions: compression and expansion
- 【Two Hooks & Two Lube Oil Bottles Included】Hooks are used to hang your brake discs, preventing them from shaking when you fix the car yourself. The two bottles of lubricating oil have the function of preventing rust and abnormal noise. They should be applied to the rear of the brake pads. Do not apply them to the contact surface of the brake pistons as this can easily cause slippage
- 【After-sales service】The tool connection is lubricated as a factory design for stable and smooth operation, which is not a sign of use.
