2002 Ford Excursion 7.3 4x4 rear brakes getting smoking hot. Noticed it on driver side first. Assumed the rotor was sticking, replaced it and the hose. Relaxed pads and found the pads on passenger side...


There are a number of issues that can cause overheating disc brakes. Disc brakes, when released, separate from the disc by the action of the rotor moving between them (since no rotor is perfectly true, there is a small about of wobble and it pushes the pads away from the rotor surface). Things that can cause this to go wrong are:

  1. Caliper pistons that have rust rings that cause sticking. This most often will happen right after or shortly after replacing old, work out pads with new ones. Because the caliper piston was extended out farther with the worn pads, its surface may get rusty. This rust can cause sticking when the piston is pushed back into the bore with the new, thicker pads.
  2. Caliper slide bolts will rust and get sticky, not allowing the caliper to release properly and re-center itself on the rotor. What you often see here is that one pad (inner or outer) is totally worn out and the other seems normal.
  3. Rusty brake lines/caliper internals can cause restrictions in the flow of brake fluid and hold pressure after the brake pedal is released.
It is highly recommended that whenever you change your brake pads, you replace the caliper slide bolts use a new brake hardware kit when reinstalling. The additional cost is almost always saved in longer brake pad life, and fewer complications.

Driver's side front brake became suddenly stuck ( and mildly smoking) on my 1991 ford aerostar xl that has been excellently maintained. The 'Rear Anti-Lock' brake light came on yesterday and stayed on, and...


yes baby it to him and replace both calipers and rotors as they will work better with your new brake pads. Do Not Do a half a job when it comes to brakes. its your family you are dealing with. calipers are cheap rotors are cheaper and pads are also cheap. its 3 hours labour to do a complete front brake job and rear brakes take 2 hours. with new shoes turn drums replace wheel cylinders and new rear brake hardware price in Canadian for front brakes under 400 price for rear under 250 American parts prices slightly different but labour times the same

Replace rear brake pads


Rear disc brake pads offer better performance and are not as affected by moisture like conventional brake shoe style brakes are. Rear disc brakes are similar to front disc brakes. The main difference is that rear disc brake systems must incorporate the emergency brake system. There are two methods widely used for the emergency brake with rear disc systems. The first system is a brake shoe inside the brake disc that is actuated by the emergency brake lever. The second is a screw style actuator inside the brake caliper. When activated the brake pads are forced into the brake disc and held tightly by the emergency brake lever.
READ COMPLETELY BEFORE STARTING
Step 1 - Identify Rear Disc Brake Components
rear_brake_pads.jpg Rear disc brake assembly includes; rear brake disc, rear brake pads, brake caliper mount and a caliper mounting screw. (Note: Some vehicles do not have the rotor mounting screw.)
Step 2 - Removing the Rear Brake Caliper Mount Bolts
rear_brake_pads_2.jpg To replace rear brake pads and rotors the rear brake caliper needs to be removed. First loosen the rear brake caliper mount bolts and remove them. Turn counter clockwise.
Step 3 - Lift Rear Brake Caliper from The Caliper Mount
rear_brake_pads_3.jpg After the caliper mount bolts have been removed, gently lift the brake caliper from the caliper mount. Inspect the caliper slides; they should move freely in the caliper mount. Remove rear brake pads and hardware.

Step 4 - Removing Caliper Mount Bolts
rear_brake_pads_4.jpg With a socket wrench or other appropriate removal tool, loosen the rear brake caliper mounting bolts. Remove bolts and lift the caliper mount and remove it from the vehicle. Remove the retaining screw from the disc mounting hole. Tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub holding on tightly, using both hands. You do not want to drop the rotor.

Step 5 - Removing Rear Brake Rotor
rear_brake_rotor.jpg Remove the retaining screw from the disc mounting hole, tap the rotor gently to release any rust that has accumulated between the rotor and bearing hub. Lift brake rotor from wheel hub, hold on using both hands and do not drop.

Step 6 - Install New Brake Rotor
rear_brake_rotor_2.jpg Check the new rotor against the old brake rotor to make sure they are the same size. Clean the mating surface on the wheel hub before the new brake rotor is installed. Reinstall rotor retainer screw.
Step 7 - Reset Rear Brake Caliper
rear_brakes_7.jpg Before new brake pads can be installed, the rear brake caliper must be reset. The reset tool winds the piston back into position so the new brake pads will fit. This style of brake caliper will not compress with a clamp tool; it can only be reset with the proper reset tool.
Step 8 - Reinstall Rear Caliper Mount and Install New Rear Brake Pads
rear_brake_rotor_3.jpg After the caliper has been reset, reinstall caliper mounting bolts and make sure the bolts are tight. Then match up the old brake pads to the new brake pads. They should be exactly the same except, of course; the old ones will be worn out. Check the new brake pads for proper fit and install any brake hardware that is required.
Step 9 - Remount Rear Brake Caliper
rear_brake_rotor_4.jpg Reinstall the brake caliper, align brake pad hardware and reinstall caliper mounting bolts. (Note: align the rear peg of the brake pad to the groove in the caliper piston.) Recheck and retighten all caliper and caliper mount bolts. Bleed brake system to relieve any air in the system. Before driving the vehicle, push the brake pedal down and let it up slowly. This operation forces the brake pads to travel to the brake rotors. DO NOT DRIVE VEHICLE until proper brake pedal operation resumes. When test driving vehicle listen for any unusual noises during the operation of the brakes.
WARNING! Always have the vehicle under inspection on level ground, in park with the emergency brake on. Always wear protective eyewear, gloves and necessary clothing before inspection or work begins. Never crank an engine over when anyone is near the battery or engine. Always have an operational fire extinguisher close by, obey all first aid instructions in the event of an injury. Never stand in front or behind a vehicle when cranked over or running. When engine is cranked over keep hands and clothing away from rotating components. Never move a car without proper brake pedal operation.

Rear brake noise after brake replacement


probably a dumb question, but if there is a backing plate, did you make sure it isnt bent and hitting the rotor? you never want to sand new rotors, although i dont think it would cause this concern. i would suggest lightly scuffing up the brake pads. this will eliminate any noise caused by the contact of the rotors and pads. if it goes away then you know its a problem with the pads/rotors.

scoring of only the inside rotors would make me think that possibly the caliper slides are frozen up. make sure they move quite freely on the slides. it is not uncommon for brake pads to score rotors though.

but brake noises at low speeds that dont' change when applying light brake pressure are usually some sort of metal or something contacting the rotor.

Front breaks are smoking


caliper is sticking or pads are sticking ,proportioning valve with vehicle jacked up and supported and wheel removed inspect pads and rotor for damage excessive wear if good- turn hub/rotor by hand have someone assist u by stepping on brake observe brake caliper stop then release brake piston should release slightly from pad try turn hub again w/out touching brake if stuck in place replace and caliper released replace pads if caliper still clamped remove caliper and inspect for leak or damage compress caliper and try brake again if does if sticks again replace caliper

Rear brakes not completely disengaging


your inside pad wore out first do to a bad caliper or frozen slide or brake hose.remove brake hose off the caliper and see if you can turn the wheel.if you can replace hose and bleed caliper.if wheel still doesn't move buy a loaded caliper,this will come also with new slides!and then bleed

97 mustang gt running threw rear brake pads


how many miles are u getting on a set of brake pads before they wear out? Have u flushed out the lines? Contaminated brake fluid can ruin the calipers, causing internal corrosion which in turn causes the caliper to drag and burn out the pads prematurely. The strange thing w/ this theory, is the fact that it's just one wheel. I would try bleeding all the lines though, to make sure u have bled all old fluid, and replaced it w/ new. Has the mustang ever been in an accident? Just wondering if caliper mounting bracket is tweeked, or some other component that the brake system is mounted to. Let me know if this is any help, and if not, if u have any more clues that might help figure this out. Good Luck

Front brake pads for 1997 ford ecscort encore


The binding of the brakes is causing the pads to overheat, which is causing the smoke. You need pull the wheel and check things out. Your caliper must be bad (not releasing). You need to replace the caliper, brake pads, and have the rotor cut (a full service parts store or shop cuts the rotor perfectly smooth on both sides), or replaced (it may be cheaper to just buy a new rotor). You should also always change the pads (and check everything else) on the opposite side. So, if u do the brakes on the driver side front, always do the front pass. side at the same time, likewise if u do rear brakes.
Whenever you do brakes u should also flush out the brake lines (by bleeding the brakes) until the brake fluid flows absolutely clear. Old brake fluid is the #1 reason for caliper failure. I've seen many times people replace brake components w/out changing the brake fluid, only to have the brakes wear out very quickly, or not function properly. good luck! hope this helps> please rate this!couontrycurt0
