The Ford Mondeo uses a hydraulic caliper braking system that must be maintained to operate properly. The brake pads are a routine maintenance item and are designed to wear out of material and alert the driver when they require replacement. The average backyard mechanic can replace a set of Mondeo pads in about an hour.
Raise the vehicle at the brake to be repaired by placing the floor jack on the frame rail near the wheel well, then pumping the lever until the wheel is off of the ground.
Remove the wheel by turning the lug nuts in a counterclockwise direction. Set the wheel aside.
Remove the caliper by turning the twin caliper mount bolts at the back in a counterclockwise direction, then sliding the unit off of the rotor. Disconnect the ABS wiring harness adaptor, if applicable, by pulling the plug apart after disengaging the catch with a fingernail.
Pull the pads free of the caliper pistons and replace them with new units. The pads are held in with small metal clips on some models, but most are not connected and will come right out. Debris or dust could cause the pads to be stuck to the piston; pry them loose with a screwdriver if necessary.
Replace the caliper by sliding it back onto the rotor, then turning the rear mount bolts clockwise. Reconnect the ABS system to the caliper by pressing the plugs together until a click is heard, if applicable.
Replace the wheel and turn the lug nuts clockwise, in an alternating pattern, until snug.
Lower the Mondeo to the ground and remove the floor jack. Tighten the lug nuts once more.
Repeat the entire process on the remaining brakes.
Use anti-squeal spray on the pads to prevent noise. It is recommended that the rotor be resurfaced when replacing the pads, for "meshing" the two components better.
Use extreme caution when working on a lifted vehicle.
