This is a really common issue. If the brake pads you used were the "cheap" ones, then that could be your issue. I have installed cheaper pads with a high metallic content only to have to remove them right away and replace with a better quality pad. (Ceramic pads are really good in your application) A couple other things to note are anti squeak compound on the back of the pads, and cleaning all contact areas on the back and sides of the pad and applying lubricant. Lastly, machining the rotors may be necessary. A clean fresh surface for the new pads to seat into may be in order. Brake squeak can be very annoying, but I'll bet if you look at these areas you can and will solve you issue.
Good luck.

Did u checked the disc? was is flat and nice? or did it had scratches along the diameter of the disc? the pads need very flat rotors for them to work,
it can be that the pads are too flat and hard because they are brand new and the disc may be deformed...have them checked
hope this helps

1999 Dodge Neon / front callipers, front brakes, rotors in front, and driver side knuckle.


things that have to be checked during a brake replacement process
the caliper pistons have to move back easily when fitting new pads
the caliper body has to move freely on the mounting pins to allow the centralization on the disc rotor
the brake bleeder nipple has to be opened when pushing the pistons back as the displaced fluid build sup pressure in the reservoir
check that the fluid level in the reservoir is not above the full line
check the brake master cylinder is operational and compensating ports are not blocked
basically the problems is that the pads are in contact with the disc and that is generating heat. that heat expands the brake fluid that has to be allowed to flow back to the reservoir
if the expansion of fluid is prevented either by over full reservoir or faulty mastery cylinder preventing the free flow back to the reservoir then the expansion applies the pad more tightly to the disc which in turns creates more heat and more expansion of the fluid
At this point and before you do anything else ,my steps would be to flush the system out using metholated spirits by filling the reservoir and then bleeding each wheel until clear fluid came out
when this is accomplished any black junk in the system is removed
fill the reservoir with new brake fluid and repeat the bleeding process until only brake fluid comes out
Metholated spirits is compatible with brake fluids and is recommended for the purpose
having cleaned out the system and ensured the free movement of the calipers on the mounting pins the pads should be in light contact with the discs and hubs should spin free after brakes are applied and released
In practice pads always touch the disc as there is no method of pulling the ads back and it is the air friction between pad and spinning disc that gives a minute clearance when travelling and if that ability is not allowed then the problems that you have will result

Squealing at the right front wheel


The brake lining's have worn away, the squealing was metal to metal (worn pad against metal disc) The worn pad will have damaged the brake disc. Very dangerous. You will now have to have new brake pads and discs fitted to BOTH front wheels to put it right. Good luck

hi from the uk have had this problem on a customers car b4 who had replaced frot calipers and pads and pedal went to floor on inspection of caliper i found that the steel spring clip that fits into two holes in the front face of caliper and must also locate behind the caliper carrierbehind two lugs was fitted incorrectly it had been fitted behind the outer pad resulting in when brake pedal off ?the caliper being floating type as it is known because it is fixed by two screw pins/bolts and moves on these pins/bolts as pads wear ? what happens is the spring fitted wrongly ? actually pushes against the outer pad and as a result the caliper piston is pushed back into its cylinder slightly as it moves on the locating pins/bolts resulting in pedal going to floor on 1st application but if pumped ? some brake pedal force is felt but is lost again when pedal released ? so try this ? remove the steel clips from both front calipers that retain caliper to carriers then press brake/pump pedal ? if as suggested above works? your pedal should pump up and remain ok when you release and still be firm when re applied ? all above is what i found on ford ford but many other models use similar calipers and spring locating recheck how this spring should locate hope this helps ? good luck

Losing brake fluid(2001 kia sportage)


Check the rear wheel cylinders if you have drum brakes on the rear. Check the master cylinder cap to be sure it's on right & snug. Use D.O.T. 3 fluid,not synthetic. If you're losing fluid there's a reason. Check the front brake pads & slides for the calipers,could be frozen with rust & eating up the pads. Fluid would seem low if the pads are shot.
