Front right disc and rear right drum 2000 focus will not bleed out

Either bleed all lines again or check master cylinder. Start with a slow thorough bleeding job making sure master is never low of fluid.

is ther a rear brake equaliser on the rear axle? this is usually spring operated that pulls up on the rear brake limiter depending on load in vehicle may be stuck in the vehicle loaded position when the vehicle isnt carrying much weight worth a look , just jack up rear end and look for spring device centre of rear axle attached to a device with the brake lines entering/exiting if there get vehicle as high as safe to do then put blocks under rear wheels then slowly lower jack and look to see if the spring device moves down with the vehicle if not this could be the problem as is exerting pressure to rear brakes so causing them to over heat keep me posted

brakes pads go with calipers and disc brakes,brake shoes go with drum brakes which has wheel cylinders.

Bleed your brakes, starting with Right rear, left rear, right front and ending with left front. You have air in the lines or a bad master cylinder. Bleeding is the cheaper of two options.

Good question, on the antilock system is a bleader too and bleade it the same way you bleade the caliper. After all is done adjust the rear brakes, they should have a drag to them.

ok there are a few things you need to check.. you said you changed the master cylinder.. did you bleed the braking system after???

• remove from wheel,,
• locate bleed valve on caliper / or unscrew one of the lines
• pump brake and push right down and hole,,
  
• repeat plugging the lines with your finger ,,
• repeat the above 2 steps a few times
• tighten the bleed screw while holding the brake right down..

if that fails ...

if that fails try adjusting the brake up.. its on the rear tires,, remove one and them remove the shield protecting the brake shoe,, see the turn bolt that adjust the pistons,, adjust that a bit until the brake is in the desired position..

check your disc pads to see if its wron out..

check your booster / change it..

make sure you are bleeding them by doing them as an abs system,do the right rear then the left front,then the left rear then the right front,the opposite wheels are how the system brakes.

I assume you mean that you replaced the front pads and rear shoes. Or did you also replace the disks and drums?? Either way you should be ok unless you also replaced the slave cylinders on the rears.
The fluid flows back up to the Master Cylinder as you squeeze the calipers and the slaves to fit the new parts in. Some people pre-fill the caliper to reduce the amount of air and make bleeding easier.Now .....Grinding better be a wrong choice of words. Possibly you spilled fluid on the pads while bleeding the lines. This will cause a binding and shuddering when you apply brake pressure. This will also make you think the lines are not bled properly because of the increased pedal pressure you are putting on the wet/lubricated front pads. If so, replace the pads. Don't try washing them with aerosol cleaner cause it takes more time and money than simply changing them.

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

Still have air inside, because you used gravity feed method.
