    grease or brake fluid would cause the grabbing,except that brake fluid will wash off with some warm soapy water.Axle grease ??more like its EP90 gear oil its thick and has a horrid smell ,and their is nothing worse than having this run up your arm or laying in it and then having a shower and going out then to start stinking when your in company especially if the company is all la de da and stuck up their own posteriors.Iam a bodgy old mechanic what else do they expect,i make al bundy look posh.Well best of british mate ,just had a thought their should be a drain hole in the back plate at the bottom to allow any oil seal leakage to drain down the back of the brake backplate,its no doubt full of crud so clean it out with a piece of wire .

Hi I have a peugeot 406, I HAVE REPLACE THE FRONT BREAK DISC AND THE BREAK PADS BUT IT STILL GIVE THAT HORABLE NOIOSE WHEN I BREAK. Its realy iritating and i take good care of my car,


Remove the brake pads from the car and smear small amount of high melting point silicone grease e.g. Carlube, at the back of the brake pads. Be careful do not put on too much and never has it touch the pad material and the disc rotor. if you do, remove it with brake clearner immediately. The squeaks noise shall disappear if you fix it properly.

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

Replace rear brake pads 2006 Chevy Impala


Hello, to replace the rear brake pads follow the following steps:

1. Lift the Chevy Impala with the jack and place it on jack stands.
2. Remove the wheels with a lug-nut wrench and set them aside. The lug-nut wrench can be found in the trunk of your Chevy Impala.
3. Remove the caliper with a ratchet and use a bungee cord to hang the caliper. Do not let the caliper hang from the brake hose, as the hose might break and cause fluid to leak.

4. Remove the brake caliper bracket from the steering knuckle with a ratchet. Set it aside.

5. Remove the break rotor from the hub. The rotor might require force to be removed; if it does, use a hammer to hit the rotor in the center, where the lug studs are located. Take care not to hit the studs.

6. Remove the new rotor from its packaging and use brake cleaner to remove the grease from the rotor. Grease is applied on the rotor in the factory to inhibit rust during storage.

7. Install the new rotor onto the hub.

8. Install the caliper bracket with new brake pads onto the rotor and fasten it to the steering knuckle. Use a ratchet to tighten the bolts.
9. Open the master cylinder reservoir so you don't break a seal while compressing the brake caliper.

10. Compress the brake caliper with a C-clamp, so that the caliper can fit over the new brake pads. Install the caliper by securing it to the brake caliper bracket with a ratchet.

Thanks

How to remove rear disc brake pads seems there


There should be two bolts on the backside of the calipers that you have to take off then the caliper will slide right off. Then to take off the break pads you just pop the old pads off and pop the new ones back in. Adding some break grease will help from seizing.

Sometimes our 2002 Jetta brakes squeak terribly especially on inclines and upon applying slow pressure. Happens in reverse too. Were told brakes are 75%.


this could be a nummber of things starting with copper grease on the back of the pads to a loose fixing spring on the calliper or if it only happens in the morning and in the cold or at the last few meters of a sopt when you are easyin up on the breaks this could be normal on certain cars due to the metal shavings in the break pads being over sized (cheap break pads) i suggest if you have mechanical knowledge you should remove callipers and copper grease the back of the pads and make sure all the clips and springs are in tack and tight if this still dose not stop it then you should invest in more upmarket break pads
hope this helps

Gear grease o new brake pads


Hi there. Normally, once you get gear oil on the pads they are toast. The gear oil soaks into them and you can't get rid of it. You will have problems with your brakes locking up if you reuse the contaminated pads. Hope this helps.

I need instructions to change the breaks (front & back) on a 2004 Hyundai Sonata.


Front brakes are simple, back brakes are a little harder. What you need is a C-clamp and some metric open ended wrenches. Lift the car and the hood, remove the tire, and open the cover on the brake fluid reservoir. Disengage the parking brake if back brakes are hydrolic. Loosen the 2 bolts that hold the caliper on and remove both pads. Compress piston with C-Clamp. If 2 piston, use a piece of wood or something that you can apply even pressure to both pistons. Be careful not to fracture the piston or rubber seal. Just be extra cautious when collapsing piston. Use a towel or anything to absorb the metal to metal force. Insert the new brake pads applying a small amount of blue grease to the back of the pad first.
Install assembled caliper. Repeat for second front. The back brakes, if drum, require more parts to pull apart. My suggestion is to lift the whole back of the car. Remove both drums, might be tough, loosen adjuster gear and pull both brake pads off. Assemble compare to other side.
