I changed the front brake pads on my 1989 honda prelude and now they squeak constantly. I took the wheel and calipers back off and looked at the rotor. It had a shiny place on the edge. In the caliper, the thin metal spring holder for the brake pads had a corresponding shiny place. I took the brake pads out and put them back in, making sure that the spring holder did not stick out into the caliper. When we drove, it did not squeak, but the first time we hit the brake, the squeaking started again. Its like applying the brakes moved the spring holder where it rubbed the rotor. Is there some trick to putting the brake pads into the caliper that I am missing?

if the caliper is ok it sounds like the flexiable hose is restrcted by the metal crimps on the hose corroded and crushing the reinforced rubber hose restricting the fluid returning back in to the system. change the hose

First you want to remove brake fluid from brake resovoir, raise front wheels off ground and set park brake or block rear wheels. Remove front wheels, keep steering wheel unlocked so you can turn rotors side to side. Loosen bolts that hold caliper end gently pry caliper free from rotor, remove caliper and remove pads, use bungy cord to hang caliper away from rotor, have rotors measured to see if they are thick enough to have machined, replace if out of specs. Match up pads with old ones, use anti- squeak red liquid and put layer on back of pads, let dry. Use tool to put pistons back into calipers, slowly put pistons back into bore while opening up bleeder screw so ABS won't be damaged. After rotors resurfaced, wash with rubbing alchohal to remove any oils from hands, install rotors and reverse putting pads back onto caliper and reinstall, torque caliper bolts to factory specs and tighten bleeder screws. Install wheels, torque lug nuts to factory specs and replace brake fluid in resovoir. Lower car carefully to ground and press brake peddle without pumping it. Any air in system should bleed out, if not get someone to help with bleeding system. Road test to ensure no squeaks or pulling, burn brakes in slowly.

check that the caliper is free to slide on the mounting pins It is necessary so that the caliper body can self centralise and let the brake pads come of the disc rotor. When the body seizes on the pins then one side of the caliper will have the pad in constant contact with the rotor and makes for bad braking and low economy

wow first post ever for country, im GOBSMACKED !!!!
wheel ?steering wheel or tire/wheel.?

hard to find, they are, all squeaks.
first is to see if possible to do, no moving (big safety issue, yes)
bounce the corners of car hard, by hand.?
jack car up spin tires. by hand,
lever them below off ground, to see of balls are shot.
inspections here, look at every inch of suspenson and parts.

Brakes, i hope nothing breaks the brakes.
The brakes all squeak this is normal try lightly pressing the brake pedal, gently while moving slow, squeaking now is 100% normal and harmless. (the pads act like Guitar strings)
Use pad glue to halt it, or ignore it like me....
the pads have wear markers, they have this device that makes noise when pads get too thin, (look at em)
bad wheel bearings.
brake backing plate bent.
caliper guide pins rusted.
and lots of other things bad or just ok , old and making noise, like
suspension "A" arm bushing rusty, or stable bar , same.

moving noise is real hard to find.

Better inspect them again. If you have grinding noise when braking. It's only one thing the brake pads are rubbing on the rotors. Now the question is which front wheel. Remove the brakes and inspect the caliper see if it's not sticking and the sliders. Then inspect the pads and the rotor for a ridge that can cause noise when the pad rubs the ridge. Just looking at the wheel won't be enough you have to remove the parts to find the problem

• A few things here.
• Pads can look good and still squeak, especially the dirt cheap ones. Quality pads are always advised. Ceramic if possible.
• You took the rotors in so I assumed that they took the required 3 spot caliper minimum test and looked for color change and worn spots/grooves.
• Brake dust is a huge cause of squeaking of brakes. Brake clean does a great job of clearing that off of the rotor etc.
• Sometimes that shudder grease (should be used every time a new pad is installed) can ware off. Did you reapply that yet? $2usd for a little packet of it. Apply it to the back of the pad.
• Did you check to see if the metal pad tracks had grease on them still? When the caliper pushes out on the pad it moves on a metal track to reach the rotor. Check and reapply if necessary.
• Sometimes pads can get a rough spot from normal ware that starts digging into the rotor. A little fine grit sand paper and a quick gentle resurfacing will fix that quick.
• One of those will be your problem. Check all I have listed. And make sure you are positive you are checking the right brakes. Brake sounds can be deceiving.
• hope this helps and thank you for using FixYa.

You will need to dig deeper. Check that the front and rear wheel bearings are smooth and tight, check each wheel for drag. pump the brake up and spin the wheel, one by one (how are they?). When you inspected the brakes what did the rotors look like? Were any of them blue in color? Did any of them have a ridge of rust on the outer and inner edge? Did you look at the old pads and see if they were waring evenly? Did the cylinder compress into the caliper easily? Did you inspect and service both sliders. Only use synthetic brake caliper lube, The non synthetic stuff doesn't last and never seize is a big no no. let me know, good luck.

Your caliper is hanging up and can be freed by removing it and grind or chip away the rust on the guides.

It could probabely be the brake pads ,some cars have worning light come on and others have this little projection of steel piece working as warning tht the pads needs replacement.
Remove the front wheel andyou will be able to see the brake calipers and the pads.
Good luck.

pistons in brake r sticking need to b stripped n cleaned
