Having problems with your 2005 Hyundai Sonata ?

There is an irritating whining/metal on metal sound coming from the front driver's side wheel. Is it my brakes and if so how hard are they to replace?

Hi, to me it sounds like you need to replace the brake pads and the brake disk so here is how you do this job:
1 undo wheel nuts and jack the side up your changing first, put axle stands under to keep car raises whilst you take wheel off, dont leave on jack as this wont support the car properly for a long time, then remove wheel

2remove two bolts holding brake caliper to rotor(this is the part that houses the brake pads you have one bolt at the top and one bolt at the bottom at the back of the caliper.

3, just before you take the 2 bolts out get a long flat bladed screw driver and put this inbetween the back brake pad and the brake disk then lever the screwdriver so you are forcing the rear brake pad back into the caliper, doing this will push the brake piston back which then enables you to fit the new ones after you have removed the old ones. So its the brake pad at the back of the disk you need to get the long screwdriver between this pad and the disk and pull the driver towards you so you are pushing the pad backwards into the caliper, this will push the piston back keep going till it stops.

4. Remove\012caliper with brake hose attached (tie the caliper up or rest somewhere so its not putting strain on the brake rubber pipe).

5 Slide brake pads off (you may\012have to gently tap on pads to remove them) and then put new ones on.\012

if you couldnt force the piston back earlier then your going to need a big g clamp to force it back now to allow you to get the new pads in if you done it earlier skip this part

6, now to remove the disk if you look towards the center of the brake disk you will see one or two cross head screws you need to undo this then the old disk will fall off with a gentle pull.
7 when you fit the new disk you need to clean it off with brake cleaner or wd40 as it has an oil coating to prevent it rusting whilst its on sale in the shops so when you buy the pads and disks make sure you ask them whats best to use to clean the surface of the disk not doing this will mean you wont stop when you press the brakes.

8 refit new disk replace the locating screw.

9 fit the new pads it is a good idea to put a bit of copper grease on the back of the pads to prevent any noise not the side that touches the disk but the back of the pads the metal part that touches the piston
Compress piston in caliper to make room for new pads with a clamp.\012Install caliper, install tire.

now repeat this on the other side.

you need to replace both sides at the same time so dont just replace the one side due to the fact if that side is low then the chances are the other side is just as low

check brake fluid level after doing this, it would also be worth putting a bit of rag around the brake fluid filler as when you push the pistons back your going to force brake fluid back into the fluid resevoir,

then before you drive anywhere get in the car and push the brake pedal a few times to ensure the pads are pushed against the disk, then you should have no problems using your car.

let me know if your having any problems.
