Replacing front brake pads on 2002 fc hino truck , which way do you turn the adjusters to losesen them

It is possible that the brakes are not adjusted properly. If the brakes are not adjusted correctly, the brake pads can rub against the rotors, causing a metal-on-metal sound. It is also possible that the brake pads are worn out and need to be replaced. If the brakes are not adjusted properly, it is important to have them adjusted by a professional mechanic.

do not attempt any adjustments. replace the front brakes when they need it. if you try to adjust the proportioning valve you will lock up your back brakes and risk loosing control of your vehicle. you risk ruining the ABS system in your car which will cost you far far more to replace than a cheap set of brake pads. the front brakes do most of the stoping, that is why they wear out much faster than the back brakes. it is VERY IMPORTANT that you DO NOT attempt to adjust your brake proportioning valve.

Cable may be seizing in the sheath due to corrosion. Remove the drums to see if shoes move outward when someone pulls the lever. If not, remove the cables from the shoes, raise the ends, and shoot oil into the sheath. Break the cable loose inside the sheath and continue oiling until the cable moves freely in the sheath.

The brake lights switch is located on, or activated by the brake pedal.

Seems it needs to be adjusted or replaced.

Good Luck

YOU HAVE TO SAFELY RAISE SUPPORT VAN ON JACK STANDS.REMOVE BRAKE CALIPER AND BRAKE PADS DONT DISCONNECT BRAKE LINE.THEN MOVE DUST CAP OR GREASE CAP.REMOVE COTTER PIN SPINDLE NUT AND WASHER.THEN THE ROTOR NUT.YOU NEED A HAYNES OR CHILTON MANUAL.BECAUSE YOU HAVE TO ADJUST WHEEL BEARING WHEN YOU REPLACE ROTORS.

That's to be expected and is completely normal.

Rear brake shoes as fitted to drum brakes can typically last up to 60k miles with periodic adjustments, but you have rear disc brakes and the shoes will typically last half of that.

Also, modern brake pads no longer contain asbestos and are now made using harder metallic compounds; the direct result is that brake discs (US=rotors) are also considered to be consumable items as they are worn down by the harder pads. It's not unusual to have to replace front discs every other pad change and rear ones with every pad change; in both cases the mileage will typically be around 30k miles on most models.

there should be adjustment under vehicle looks like bolt attached to cable just back off nut and loosen bolt 

For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!! For front brake pads. First you must verify yours front brake disc diameter: 280 mm or 288 mm. (On my car y have 288 mm). After that you can buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow: 1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose! 2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper. 3. Now you must thoroughly clean the brake calipers (free of grease). 4. Remove outer brake pad from brake carrier. 5. Pull inner brake pad out of brake caliper piston. 6. Check up the brake fluid level on the reservor, and emptying if neccessary! 7. Push piston back into brake caliper housing. 8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward). 9. Install outer brake pad into brake carrier. 10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm. 11. Install both caps. 12. Insert retaining spring into brake caliper housing. Important: Depress the brake pedal firmly several times while the car is stationary so that the brake pads adjust to their normal operating positions!!! Check brake fluid level and top up if neccessary!!! Please Rate my Response! Thanks!

Bleed the master cylinder first. You have to do that before you belled any calipers or wheel cylinder.

There should be a rubber insert in the back of the wheel assembely,take it out and you can adjust the brake tighter or looser by turning the adjusting wheel
