[QUOTE="Chris, post: 419877, member: 1"] When you apply pressure to the brake pedal, the pivot rod moves through the firewall and compresses the brake fluid inside the master cylinder. To achieve smooth pedal operation, the pivot rod is supported by a teflon bushing. This bushing comes in contact with the rubber dust boot behind the brake pedal. The friction created between the two during contact makes the common squeaking noise. Synthetic grease is designed for this purpose and works great on teflon. Once the grease spreads throughout the bushing, the noise should disappear for good. [ATTACH=full]112251[/ATTACH] [B]Materials Needed[/B] [LIST] [*]Rubber gloves [*]Synthetic grease [*]Safety glasses [/LIST] Make sure the source of your noise is originating from the brake pedal. This noise will occur when your Jeep is stationary. [SIZE=18px][B]Step 1 – Lubricate teflon bushing[/B][/SIZE] Behind the brake pedal you'll see a rubber boot. This boot is designed to keep the grease on the bushings and dirt out. Carefully pull the boot towards the firewall to expose the white teflon bushing. Apply some synthetic grease or similar lubricant to the surface of the bushing. Press and release the brake pedal several times to spread the grease throughout the bushing. You may have to repeat the application several times through the next week to reach all areas on the bushing with a dry surface. [ATTACH=full]112252[/ATTACH] Figure 1. The brake pedal boot.
