Tip & How-To about Hyundai Elantra

Tips for changing break pads, money saving tips!

Make sure the vehicle is cooled down - If you have recently driven, you may be working with extremely hot pads, calipers and rotors. Be sure that these parts are safe to touch before moving on.

Loosen the lug nuts on the wheels - Using a lug wrench, (one is usually provided along with the car's jack,) loosen each of the lug nuts that hold the wheels onto the car about two thirds of the way

  1. Jack the car up - Locate a safe place to position the car jack under your car. Check the user's manual or check for markings that indicate where to place the jack. Put some chocks behind the wheels that are on the ground to stop the car from rolling forward or back. Carefully jack the car up until the wheel can be removed easily. Place a jack stand or blocks under the frame of the vehicle. Dont trust the jack alone. Repeat for the other side of the car so that both sides are securely supported.
  2. Remove the wheels - Finish loosening and remove the nuts. Pull the wheel straight out towards you to remove it.
  3. If the wheel rims are Alloy and are either seized or partially seized on the studs, try kicking the tyre at the bottom with your foot a few times and hopefully it will move. when this occurs, you should clean the studs, stud holes, Rotor mounting surface, and the rear mounting surface of the alloy wheel - with a wire brush and apply anti seize compound before refitting the wheel.
  4. You should now be looking at the rotor (a large, flat metal disc) and the caliper (a large clamp-like device wrapped around the top of the rotor).
  5. Remove the caliper bolts - There are many different ways that the caliper is secured and different Caliper designs necessitating different removal procedures. The mounting position also depends on the Caliper design and whether it is an all one piece, a two piece, or a more complex design Caliper. All One piece Calipers are generally secured with between 2 to four bolts at the inside of the stub axle housing. Spray these bolts with WD-40 or to aid in removing them. Using a correct size Socket or Ring spanner, loosen and remove the bolts MAKING ABSOLUTELY SURE THAT THERE ARE NO SHIMS FITTED BETWEEN THE CALIPER MOUNTING BOLTS AND MOUNTING SURFACE. If there are they must be refitted as they were or the Caliper will not sit correctly.
  6. If any do fall out unexpectedly, you will need to refit the Caliper without the brake pads and using a combination of feeler guages, measure the difference between the pad mounting surface to the Caliper at the top and Bottom. Then, work out the difference/s and allocate the shims accordingly.
  7. Alternatively, many Japanese vehicles use a 2 piece sliding Caliper that only requires the removal of 2x forward facing, upper and lower, slider bolts, and NOT the removal of the entire caliper. These bolts are often 12 or 14mm heads.
  8. Additionally, if these caliper are completely removed, it is much more difficult to fit the brake pads into them.
  • Check the caliper pressure - The caliper should now move a slight amount if you shake it. If not the caliper is under pressure and it may fly off when you remove the bolts. Take extra precaution to not be in its path, whether it is loose or not.
  1. Next, have a piece of light tie wire handy, about a foot long, before you proceed.
  2. As the caliper will still be connected to the brake line, hang it up carefully by the wire, in the wheel well, so that it doesn't drop and have any weight on the flexible brake hose.
  3. Remove the top of the Brake Master cylinder from under the engine hood and inspect the fluid level before the pistons are 'Squeezed' back to enable the new brake pads to be fitted. Many mechanics draw some fluid from the master cylinder before proceding to squeeze the brake Caliper pistons.
  4. However, a better method is bleed the old Caliper fluid off by fitting a brake bleeding hose to the Caliper nipple, place the hose in a small bottle and undo the bleeder nipple as the pistons are squeezed. They are easily squeezed with one hand using large 12 inch water pump pliers - much easier than C or G clamps. So, the pliers are held in one hand and the bleeder spanner in the other. If it was not intended to bleed the brakes they still do not need to be, but the old fluid will have been removed from the Calipers at the same time as squeezing the pistons fully inwards. Repeat this with the other pad. Note that there is normally only one piston to be compressed for the right front and likewise for the left front.
  5. Remove the pads - Note how each brake pad is attached. They typically snap or clip in with attached metal clips. Remove both pads. They may take a little force to pop out, so take care not to damage the caliper or brake line while getting them out.
  6. Put the new pads on - Spread the special anti seize lubricant that came with your pads, (if it's not provided you can get it at any auto store,) sparingly on the metal contact edges and on the back of the pads, the surface of any shims and the piston pad contact area. This will prevent a lot of annoying squeaking. Attach the new pads exactly the way the old ones were attached.
  7. Check the brake fluid - Check your vehicle's brake fluid level and add some if necessary. Replace the brake fluid reservoir cap when finished.
  8. Replace the caliper - Slide the caliper slowly back over the rotor, proceeding easily so as not to damage anything. Replace and tighten the bolts that hold the caliper in place.
  9. Put the wheel back on - Slide the wheel back into place and hand tighten each of the lug nuts snug.
  10. Lower the car - With one side of the car supported by the jack, remove the block or stand on that side and slowly release the jack and to lower the car. Repeat for the other side so that both wheels are back on the ground.
  11. Tighten the lug nuts - Moving in a "star" pattern, tighten one lug nut, then one across from it until each nut is fully tightened to torque specification.
  12. See technical info to find the torque spec for your vehicle. This will insure the lugs have been tightened enough to prevent the wheel coming off or overtightening.
  13. Start the vehicle - Making sure the vehicle is in neutral or park, pump the brakes 15 to 20 times to insure proper seating. Push the brake pedal and put the vehicle in gear if it rolls more than a foot put the vehicle into park.
  14. Test your new brake pads and installation - Going no more than 5 MPH on a quiet residential street, brake like normal. If the vehicle seems to stopping normally, repeat the test and go up to 10 MPH. Repeat several more times, gradually going up to 35 or 40 MPH. You can also go 5 MPH in reverse and brake. These braking tests ensure there are no issues with your brake-pad installation, gives you confidence when driving on main streets and helps "seat" the brake pads into place.
  15. Listen for problems - When testing, if you should hear a grinding sound such as metal on metal, you probably have the brake pads reversed (i.e., the inside surface incorrectly facing out). This should be corrected immediately. Note that the new brake pads may squeak a little bit until they are completely broken in.

brakes rubbing

it sounds like your caliper is sticking you may have to take off your brake pads and rotor and grease up the caliper you can have the best rotors and brake pads on your vehicle but without the caliper working as it should it will wear down the brake pads and rotors quickly

overheating brakes

I think the problem is the brake pad or caliper, brake pad are too thick or the caliper are not good casted.
First try to confirm if you get a right brake caliper ,then confirm the brake disc ,brake pad, if they all ok, tear down the bracket of caliper, put into brake pad, then put into brake rotor.

2002 Honda CRV rear brake running hot. Taken to mechanic says, needs new calipers, brake pads and rotors. Reasonable assumption or can calipers be repaired with kit, rotors re-machined and new pads installed. If I go with his fix what should a reasonable charge be? And how far can this vehicle be driven? I can do this work myself, but car is 100 miles away from me with daughter.

Although calipers can be rebuilt, it's usually more cost effective to buy a rebuilt caliper. As far as turning the rotors, modern day rotors are much thinner than those of 20 years ago. Where in times passed you could turn down rotors 2 or 3 times before replacement, taking a few 1000ths off a newer rotor will take it under factory specs. As far as a reasonable price goes, the full job can run anywhere from $400-600 depending on the shop doing the work. Doing the job yourself you can save a few hundred dollars in labor and another $100 in parts markup.

how do i change my brake pads on my honda accord ex 1994


Fig. Fig. 1: The pads can be viewed through the inspection hole
Remember that you are looking at the profile of the pad, not the whole thing. Brake pads can wear on a taper which may not be visible through the window. It is also not possible to check the contact surface for cracking or scoring from this position. This quick check can be helpful only as a reference; detailed inspection requires pad removal.


Fig. Fig. 2: It is best to remove the pads to check for taper


See Figures 3, 4, 5, 6 and 7

CAUTION If the car was recently driven, the brake components will be hot. Wear protective gloves.

  1. .
  2. Loosen the lug nuts, then raise and support the vehicle safely.
  3. Remove the wheel.
  4. As required, separate the brake hose clamp from the strut or knuckle by removing the retaining bolts.
  5. Remove the lower caliper retaining bolt and pivot the caliper upward, off the pads.


Fig. Fig. 3: Remove the lower caliper retaining bolt ...


Fig. Fig. 4: ... and pivot the caliper upward, off the pads

  1. Remove the pads, shims and pad retainers.


Fig. Fig. 5: Remove the pads, shims ...


Fig. Fig. 6: ... and pad retainers
To install:


Fig. Fig. 7: Front brake pad components

  1. Clean the caliper thoroughly; remove any rust from the lip of the disc or rotor. Check the brake rotor for grooves or cracks. If any heavy scoring is present, the rotor must be replaced.
  2. Install the pad retainers. Apply a brake-quiet compound (available at most auto parts strores) to both surfaces of the shims and the back of the disc brake pads. Do not get the compound on the braking surface of the pad.
  3. Install the pads and shims. The pad with the wear indicator goes in the inboard position.
  4. Push in the caliper piston so the caliper will fit over the pads. This is most easily accomplished with a large C-clamp. As the piston is forced back into the caliper, fluid will be forced back into the master cylinder reservoir. It may be necessary to siphon some fluid out to prevent overflowing.
  5. Pivot the caliper down into position and tighten the mounting bolt to 33 ft. lbs. (45 Nm).
  6. Connect the brake hose to the strut or knuckle, if removed. Install the wheel and lower the vehicle to the ground.
  7. Check the master cylinder and add fluid as required, then install the master cylinder cover.
  8. Depress the brake pedal several times and make sure that the movement feels normal. The first brake pedal application may result in a very "long" pedal due to the pistons being retracted. Always make several brake applications before starting the vehicle. Bleeding is not usually necessary after pad replacement.

Braking should be moderate for the first 5 miles or so until the new pads seat correctly. The new pads will bed best if put through several moderate heating and cooling cycles. Avoid hard braking until the brakes have experienced several long, slow stops with time to cool in between. Taking the time to properly bed the brakes will yield quieter operation, more efficient stopping and contribute to extended brake life.
  1. If equipped, enable the SRS system and connect the negative battery cable.

Steering wheel shakes when brakes are applied lightly

Sounds like a warped break rotor. Needs breaks.
