First did you bleed the brakes after replacing parts? Grinding? Did you replace or resurface rotors?

Hi i have a honda XR250 03-04 *** import and my brakes are spongy? I have changed the disks and pads and i have bleed the brakes but are still spongey like not sharp poor breaking thanks

The new pads may require a few kilometers of riding before they bed into the new disks.
Failing this, try reverse bleeding of your brakes. Use a large syringe and tube. Fill the syringe with brake fluid, being careful to remove all air from the syringe and tube. Connect to bleed nipple, and with the brake lever fluid reservoir cap removed, compress the brake fluid back up to the reservoir. Your syringe will need to be large enough to contain more fluid than caliper and line combined for this procedure.

Break noise when you press break

I am not sure what kind of noise you are talking about as you did not post it. Jack up the car. grab the wheel top and bottom and try to move it. do the same side to side. if it will go up and down you either have a bad bearing, or a bad ball joint-if it move side to side, you have a bad tie rod. Pull off the wheel. Check that the pads are still good. Grab the brake caliper and try to move it. if it moves-check that the tightness of the bolts that hold it to the A-frame. If the pads are not worn, and everything else is tight, what you are most likely hearing is the metal in the pads grinding against the rotors, or brake dust buildup.If it is a squealing noise, Using a air compressor with a blower tip, blow out the caliper. You may also(for large buildup of brake dust) get a can of break cleaner and spray off the rotor and caliper. If grinding(and the pads are good), It may also have lost the noise reduction pad behind the brake pad that reduces that noise. This will not hurt the vehicle, but if you want it fixed, you will have to replace the pads, and have the rotor turned at you local brake shop, machine shop, or parts store. Usually about $5-$10 per rotor.

Replaced brake pads, rotars and callipars and brakes feel spongey. did bleed all 4 callipars til fluid came out and replaced brake fluid in master cylinder, still spongey can't figure it out.

U need the special anti-lock brake (ABS) bleeder adapter to get the air out of the ABS hydraulic control unit, that is why the spongy feel the system is no completely bled of air unless you hook up the tool that holds the hydraulic control valves open for bleeding

Grinding sound when I break and after I break. It

You are correct. The pad has worn down to the steel backing pad, and now you will have to replace your brake rotor as well.

When I put on the breaks there is a grinding sound. I just had it inspected.

This can be caused by a sticking brake caliper. I would check the calipers for proper operation. Also check the condition of the brake rotors and pads. Hope this helped and best wishes.

Rear brakes are grinding on one side.

Replace the pads and see if rotor that pad was grinding on can be resurfaced.If not replace it.While you have it apart lube the caliper slide's with anti-seeze or a brake lube so the caliper can move smoothly.

Brakes are making loud grinding noise when slowing down to stop or on an incline

Ok, it could be a few things, 1. bad break caliper. 2. if you have ceramic breaks, it could be a cracked brake pad, and if they are not ceramic they can still be cracked. 3. if you drive a lot then it could be that you need new breaks again.. 4. also have your back breaks checked along with the front ones..

When pressing on the break a loud grinding noise comes from beneath the car

Your brake pads are shot, and the noise you hear is the metal of the caliper grinding on the rotor. If this just started happening, you can probably save the rotor and just buy pads. If the rotor's surface is gouged or scraped badly, you'll need new rotors too. Don't drive the car unless you are driving it to a shop to have the brake work done - it's very dangerous as you have greatly diminished stopping power.

Oh, and if they try to tell you that you need new calipers too, trust me - you don't. When the calipers grind on the rotor, the rotor takes the damage. Pay for new rotors, new pads, and I'd have them do a full flush and fill of the brake fluid too (never hurts to do this).
