Service brakes

2 reports
“2004 Mitsubishi Montero Limited: Hydraulic Brake Booster is malfunctioning, making a ("gobble-gobble", squirrel-like chirping sound) almost every time the brake pedal is pressed. Hwy driving, without the use of brakes, the frequent "chirping" sounds still occur. Under medium to heavy braking, the vehicle shudders and shakes. This specific sound is made in all gear selections and even when the car's battery is on/engine off. Upon inspection of the hydraulic brake booster under the hood, the unit shakes when the chirp sound is made. Duration of the sound lasts around one second and it happens frequently (5-10 times per minute).”
