Cadillac CT4 Brake pressure is uneven Inspection at your home or office.

Common reasons for this to happen:

• Stuck Caliper: Perhaps the most obvious reason for brake pressure to be uneven is a stuck caliper. If the caliper is not free to slide back and forth on the slide pins, it will not engage the pad correctly. In fact, it might never completely disengage from the pad, creating a constant drag that can be noticed even when the brakes are not being used.

• *Damaged Brake Line - Sometimes, brake line damage isn’t visible. If the inner liner of the line has been damaged, it can act like a restrictor, blocking the flow of fluid to the caliper and reducing braking force.

• Stuck Piston: The piston in the caliper needs to move back and forth freely, but if part of the seal has become wedged between the body of the piston and the caliper, it will not move as needed. This can also create uneven brake pressure.

• Bad Proportioning Valve: The proportioning valve is located under the hood and is responsible for adjusting the fluid pressure sent to the rear brakes. If the valve begins to fail, uneven brake pressure can result.

• Pad Contamination: Another possible cause of brake pull (uneven pressure) is if fluid has contaminated the brake pad. This can be brake fluid, grease or even oil.

• Using Two Different Types of Pads: If you have replaced the pads on one side the car but not the other (which is always a no-no), there’s a chance you’re using two different types of pads. Different manufacturers use varying pad materials with very different performance characteristics.

• Uneven Tire Pressure: Oddly enough, uneven tire pressure can masquerade as uneven brake pressure. Check your tires to ensure that they are properly inflated – this can be an inexpensive, hassle-free fix in some situations.
