Grand Cherokee
Brake Problems
The Jeep Grand Cherokee was manufactured with four-wheel CD brakes in succeeding replica second childhood, and the components can wear absent and have need replacement periodically, simply due to usual driving. You can jewel away equitable what the complication is with the braking course, using minimal tools and skill, in less than an lifetime, generally.
Listen for Noises
The most regular complication with worn braking components is a squealing sound emanating from the wheels. This is due to the invent of the Grand Cherokee's brake pads, which insert a metal flange that Testament scrape the rotor when the pad's facts wears below a useable common. This is to alert the Chauffeur of worn pads, which should be replaced straightaway. Another sound that is bourgeois is the metallic grinding of a badly worn rotor, when the caliper presses the pads against it. This can be caused by a defective or damaged rotor, or a seized caliper. The rotor must maintain a perfectly round surface, and when it is heated and cooled beyond the manufacturer's specifications damage can occur in the form of "warping". This warped rotor will not rotate well, and will catch the pads and cause a vibration.
It should be little to turn the rotor by ability, and the pads should not adjust any noises during its revolution. Urgent on the brake pedal should break the rotation, and the rotor should be at liberty of rust and debris. The masterly cylinder, located underneath the hood in front of the Chauffeur, should enjoy a entire and flush fluid reservoir. The master cylinder can be adequate with DOT-3 braking fluid by uncapping the plastic top and carefully pouring fluid into it.
Operate the Brakes
The brake pedal should be undeniable and fixed, applying impact to the brakes in an still and controlled fashion. Whether the brakes are "spongy", or decrease Correct tension, then there could be air in the brake lines. This air can be forced away and replaced with brake fluid by bleeding the lines. The indivisible bleeder nipples are located in the rear of the caliper, and can be turned in a counterclockwise plan to direct the lines up. Press the brake pedal while refilling the masterly cylinder, pushing exhausted fluid and air out of the bleeder nipple. Once the fluid coming out of the nipple is clean and constant, secure the nipple by turning it clockwise. If the pedal is excessively firm, then the master cylinder's internal seals and components could be damaged and require replacement.
Brakes at speed
The braking system could experience "dragging", pulling to one side, or a harsh vibration when used at speed. Damaged or worn rotors can be a bent on hazard; cause not impel the Jeep in this contingency.
Inspect the Brakes
The first-class means to complete the creator of a crunch is to physically study the braking transaction by removing the wheels and looking at the rotors, calipers, and pads. A seized caliper can cause dragging, as it will not release the pads completely, and most times it must be totally replaced with a new unit as they are not typically serviceable.Glazed Rotors
A more common problem with the Jeep's rotors and pads is "glazing", or heat damage to the surface of the components caused by excessive braking (usually in downhill conditions). Different from warping, glazing can cause the surface of the rotor or pads to become smooth, giving decreased performance or even a total lack of braking ability. You must replace the damaged parts, as they cannot be repaired.
