Brake bleeding front brk

Bleed master cylinder ,with brake lines disconnected,then connect brake lines and bleed each brake line at master cylinder. then right rear brake,then left rear brake,then right front brake and last,left front brake.

Same way you do brakes but you use the line as-a bleedeump it up hold it and release line ,tighten up again pump it up crack the line tighten and no'more. Refill at cap uses brk fluid

your probably going to have to bleed the entire system.1st try & bleed the master cyl.
basicly the same as you would bleed the front/rear brakes. pump pedal & hold while someone
loosen the brake line on the master cyl. after m/c is bleed move to r/r,l/r,r/f,l/f wheels in
that order. if you have abs brakes & you got air in the pump a scan tool may be needed
to bleed properly.

First, there is NO Pumping of the brake pedal
involved in bleeding brakes

I think your smart enough to know you
need to replace both rear brake hoses,
before you proceed with the bleeding

The brake system bleeding procedure differs for ABS and non-ABS vehicles. The following procedure pertains only to non-ABS vehicles. For details on bleeding ABS equipped vehicles, refer to the ABS procedures later in this section.

WARNING Make sure the master cylinder contains clean DOT 3 brake fluid at all times during the procedure.

1. The master cylinder must be bled first if it is suspected of containing air. Bleed the master cylinder as follows:
   1. Position a container under the master cylinder to catch the brake fluid.
   2. Loosen the left front brake line (front upper port) at the master cylinder and allow the fluid to flow from the front port.
   3. Connect the line and tighten to 24 ft. lbs. (32 Nm).
   4. Have an assistant depress the brake pedal slowly one time and hold it down, while you loosen the front line to expel air from the master cylinder. Tighten the line, then release the brake pedal. Repeat until all air is removed from the master cylinder.
   5. Tighten the brake line to 24 ft. lbs. (32 Nm) when finished.
   6. Repeat these steps for the right front brake line (rear upper port) at the master cylinder.
      

WARNING Do not allow brake fluid to spill on or come in contact with the vehicle' finish, as it will remove the paint. In case of a spill, immediately flush the area with water.

1. If a single line or fitting was the only hydraulic line disconnected, then only the caliper(s) or wheel cylinder(s) affected by that line must be bled. If the master cylinder required bleeding, then all calipers and wheel cylinders must be bled in the proper sequence:
   1. Right rear
   2. Left front
   3. Left rear
   4. Right front
2. Bleed the individual calipers or wheel cylinders as follows:
   1. Place a suitable wrench over the bleeder screw and attach a clear plastic hose over the screw end.
   2. Submerge the other end in a transparent container of brake fluid.
   3. Loosen the bleed screw, then have an assistant apply the brake pedal slowly and hold it down. Close the bleed screw, then release the brake pedal. Repeat the sequence until all air is expelled from the caliper or cylinder.
   4. When finished, tighten the bleed screw to 97 inch lbs. (11 Nm) for the front, or 66 inch lbs. (7.5 Nm) for the rear.
3. Check the pedal for a hard feeling with the engine not running. If the pedal is soft, repeat the bleeding procedure until a firm pedal is obtained.

Hope this helps to solve it; remember to rate this answer.

You still have air in the system and must continue to bleed the system to get rid of it.Also you may need to pump the brake peddle for a couple of minutes to bring the brake pressure up again when the job is done.Do not continuously pump the brake peddle.Have a friend depress the brake peddle slowly as you loosen off the bleeder screw,have them push it to the floor and hold it ,tighten the bleeder screw.Foot off the peddle and repeat. Keep an eye on the fluid level in the master brake cylinder and add as needed. This can be a frustrating job and can take a lot longer than you might think.
Just relax, take your time,don't panic.Good luck

normally, the brakes are bled starting from the furthest brake to the closest with respect to the master brake cylinder. the sequence is : right rear, left rear, right front, left front. pump the brakes until pressure is built up. do this rather slowly. while keeping downward pressure on the pedal, open the bleed screw slowly. the pedal will go to the floor. hold the pedal on the floor and tighten the bleed screw. do this until no air is observed. keep the reservoir. repeat with the rest of the brakes following in sequence

Why are you installing a master cylinder? Do you have the skills and tools to do the job? If so what do you want shown to you and in what format online

Might have air in the line.. Did you bleed the lines properly when you did the work ?
Take the cap off of the master. Open the pass side bleede valve.. Let it run out while you keep the master full at all times.. Let a few pints or so run through.. Clsoe everything tight before toutching the brk peddle..
It could also be a bad break line.. The flexable one that runs from the metal line to the calipar..

loosen the front brake line that goes to the master cylinder fill master cylinder up with fluid and bleed it first by attaching a flexible line from master cylinder front brake side submerge that line into jar of brakefluid keeping air from entering line get someone to pump brake pedal while ur holding line in a jar keep refilling the brake resivoir so no air gets in, once the master is bled front brake side then reattach the origional brake line then remove bleed screw from caliper and let fluid gravity flow down to calliper then bleed the normal way. more than likely your master cylinder has air trapped in the front portion good luck
