Front brakes continue to squeak.

to help with pad squeel when you take brake pads out clean all rust from the caliper where the pad slides and put some copper grease on the areas that contact this should help, while you have caliper off check the slider pins too as they may have rubber stuck to them, if they do buy new pins or scrape rubbish off and copper grease them up too, hope this helps.

How to stop squeaking breaks on my 2007 nissian maximum

Brake squeak can be from a wear indicator which is a metal clip that touches the brake disc when the pads wear thin. If there is plenty left on the brake pads removes them and cover the BACK and the top and bottom bit of the pad where it meets the housing/caliper with copper grease. NEVER APPLY where the pad front meets the disc

I have a 1997 600 bandit and I have replaced the front discs with new kagazumi discs and new pads off ebay,my problem is there is a squeel coming from the feft disc (viewed from on the bike) I have since...

It is not uncommon for discs including car discs after changing pads for the disc to squeel.

Because the disc will inevitably wear with use, the old brake pad that causes the wear will also be worn to fit perfectly to the wear on the disc as at engages, whereby grooves in the disc that are formed will be identically paired to that on the brake pad.

Squeeling is also common for old pads, as well as poor quality badly manufactured cheap pads, or excessive use of brake pads - where they get burnt and are too hard against the disc or dust fibres from the brake pad get caught within pad and disc. It could even be a combination of these that causes squeeling.

When you change the pads which are now new and being smooth and unworn they do not mate up anymore with the groove marks created from the wear of the old pads. The discs when brake pressure is applied will always vibrate to some extent, even on new bikes, however if imperfections exist such as the fact there is no wear marks from new pads rubbing against the old disc with its worn imperfections or even improper fitting etc occurs - they will sing in a high pitched squeel at certain speeds, even with good quality pads.

Other than ensuring all items are set up correctly, get a good quality brake pad and if it continues squeeling consider replacing the disc rotar itself or get the old one machined by a mechanic shop to be smooth again.

Wher do you spray anti squeal on brakes to get rid of squeak?

If you have a "squeal" when you apply the brakes, spray the anti-squeal spray on the rotor. If the brakes are "squeaking" when you go down the road, it's probably the caliper moving side to side on the pins. Remove the pins and apply synthetic brake grease on the pins.

Good Luck

Brakes ,in front, act like the brakes are rubbing metal to metal but not all tyhe time....check the brake padsd and they are good

what you may be thinking is metal is just hard pads,,,or even dry pads? try striping the barkes out and putting a thin smear of "copper grease" on the back's of the brake pads before you refit them,,,,the copper grease stops the pads from screeming when you push the brake's down,,,,only put grease on the backs of the pads dont get any grease on the brake pad fronts!!!

How to slacken rear brake shoes to replase disc

Hi Ricky

Your car has disc brakes so you need to release the brake pads not shoes (they are for drum brakes). That should help when you buy a new set.

Loosen the split pins which hold the pads in the caliper. You should then be able to push the pads out. It sounds like the pads are worn down so much that the caliper pistons are at their full reach.

Once you have slid them out, you need a piston retractor tool to push the pistons back in the caliper in order to be able to fit the new pads.

SLide the pads in, use copper grease on the back surface to stop them squeaking. Once done, pump the brake pedal to set the pads and the job is finished.

We recently replaced the front brake pads and turned the roters on our 2004 PT Cruiser. However, when applying the brakes on a hard quick stop, it makes a god-awful griding noise. Doesn't do it with a...

Brake repair is pretty simple as long as you know what you are doing. That's the reason why mechanics who do know have a brake adjusters license as extra security for the consumer. If someone repaired your brake system and unlicensed would be unhelpful when you get into an accident and file a claim from insurance. Enough of that, I think you get the picture.

  • Ensure that the piston in the caliper was pressed in all the way, it's just better whe a piston is bottomed out.
  • Clean the caliper slide rails (part of pad resting on the caliper) with emery cloth, free from rust and debris.
  • Apply a thin film of white lithium grease on the rails. This will help the pads to slide more easily and keep it from seizing. Do not over do it and avoid contaminating any area of contact when brakes are applied.
  • With a die grinder and a SOS pad scuffing wheel (you can use any tool similar as long as you achieve our goal), scuff the disk brake rotor in one circular direction. If it was turned professionally you'll see directional scuff markings around the rotor and no need to do this step.
  • The brake pads should be ground off a max of 3 deg on it's top and bottom edges. This will prevent brake chatter in it's initial operation.
  • With the brake pad material facing down, spray the backing plate of the pad with brake quiet (blue). This serves as a vibration damper keeping the squeeling noise down when brake action is applied.
  • Put the parts together, make sure there's film of white grease to parts that need to slide on each other e.g. caliper guide pins, pad rest, caliper rails.
  • Bleed the brake system starting from the furthest wheel from the brake master cylinder, moving up to the nearest as the last one. This why it's good idea to bottom out the pistons.
  • To set the pads and break-in the contact surfaces of the system, speed up and apply the brakes, stomping on the pedal to a full stop. Brake like it's an emergency stop, make sure when you stomp it, a full revolution of the rotor was accumulated to evenly set the pads in.
This should be worth something, please rate this for my effort. Thank you.

Tools req. and approx difficulty level(1-10)for brake check and change pads please on toyota previa 2.3 petrol 7 seater

to check the brakes you can look through the wheel to see the pad thickness(1/8th min)then run you finger over the disc(rotor)to make sure you don have to much of a lip around the edge.(1/32 max.)as rotors only last around 40k and pads around 30k, i would change both together,difficulty 3/10 for diy req pliers/mole grips(to grip brake pipe)/tyre iron(to force pistons apart,take off filler cap first)phillips screwdriver to take out screw in rotor,and a hammer
to release rotor from rust on the back of it.a range of metric spanners/ remove caliper from bracket and copper grease for the back of the new pads(to stop them squeeking).
put together the opposite of taking them apart,keep all bits in hubcap on top of wheel(you never have bits left over if you do this...)and prise apart pistons before you take caliper off the car,then apply molegrip to rubber pipe so they dont close up.
