I have replaced rear brake pads and vacum bleeded and then the front brakes start overheating like they are engaged all the time. This year only has a Load Sensing Proportioning Valve (LSPV) witch balancing front/rear brake force acording to vehicle load. The front brake overheating begun after I bleaded that LSPV component. How this LSPV work? Any sugestions?

The Brake caliper is usually held on by 2 bolts. Some of the bolts are Allen wrench type, usually about ¼ inch or 5/16 inch. Remove and the complete brake caliper can be lifted off the rotor. The pads can now be removed. Before installing the new pads you must first return the pad piston to their original position in the caliper. Open the hood of the engine compartment and remove the cover on the master cylinder. This allow the brake fluid to be returned to the master cylinder. To return the pad piston to the original position you will need a C clamp and a flat piece of metal like a small flat file. Put the flat piece of metal on the piston and use the C clamp to put pressure on the piston. Tighten the C clamp slowly and you will see the piston slowly retract into the caliper body. Now you can insert the new pads into the caliper. Mount the caliper over the rotor and reinstall the 2 bolts.

When I change my front brakes, I use a "C" clamp to slowly push the piston back in. (You can get them for a few dollars at Wal-Mart, etc.) Make sure you open the brake fluid reservoir while compressing them, as the fluid level will rise; but don't leave the reservoir open too long, as brake fluid will absorb water from the air.
For the parking brake, I'm not sure. I think the parking brake often works off of the rear brakes, so changing the pads should have helped there. Maybe air in the lines? Do you have any trouble with "soft" or "mushy" brakes when you use them? If so, you might want to bleed the system, to get any air out - it can be dangerous.

You are correct in assuming the proportioning valve,but it may not be bad,if it detects,loss of fluid pressure,it will shut down those brake lines.Try bleeding the master cylinder,then the wheels,and you may have to do it a couple of times,this will allow the proportioning valve allow the wheels with fluid pressure,if this was at all helpful,please rate,thank you,

Dear Sir,
Brakes (pads and discs) wear count on your use in millage/km not on time when they replaced, but a year is also good time , it may cause of minor dust inside pads get it clean. it will solve your problem.
Thanks.
