Brake fluid coming out of rear wheel brake asembly

Sounds like you have a leak in the drum brake wheel cylinder. They happen, and more often than you would expect.

You'll see in the pictures, one is the new part and the other shows where it is on your truck.

If the cylinder went bad, you'll see brake fluid leaking, even slightly, out of the rubber boot on either side of the cylinder.

sounds like only one side of your master cylinder is working, replace the master cylinder.

start from the fartherest place from brake master cylinder, that will be the rear passenger side wheel. it takes two people to bleed brakes. you will find the bleeder valve screws at the top of inside of the rear drums on both rear wheels, have someone pump the brakes up, will take at least 4 pumps of brake pedal, at 4th pump keep pressure on pedal while you break loose the bleeder valve on the rear wheel, fluid will come out and brake pedal will go down to floor, keep pressure on brake pedal until you've tightened the bleeder screw back [note] you'll only have to back the bleeder valve out about a half turn until you see the fluid come out. after you've done the rear brakes add brake fluid to the master cylinder as it will be low. then go to the front passeger side and you will find the bleeder screw on the brake caliper. repeat the same proceedure as back. remember that pressure on the pedal is a must until you've tightened those bleeder valve screws back or else it will **** air into the brake system. suggest that you bleed all 4 wheels not just the back. after you've bled the front make sure you add more brake fluid back to the master cylinder, it will be low again. hope this helps and thank you for choosing fixya.com

There only a few things that would cause this that you need to check, first start at the front wheel that doesnt work, have someone applie the brake open the bleeder screw if fluid sprays then caliper is bad or caliper slides are frozen, if no fluid comes out then you have a bad brake hose at that wheel, do the same to rear if fluid comes out of bleeder in rear then wheel cylinders are no good if no fluid comes out then brake hose to rear wheels is no good, make sure to have pedal pressed and repush pedal when checking the rear. hope this helps.

Here is the procedure from the service manual. I would add just one thing. Do each wheel in this order

1. right rear wheel
2. left rear wheel
3. right front wheel
4. left front wheel

BLEEDING

HINT: If any work is done on the brake system or if air in the brake lines is suspected, bleed the air from the system.

NOTICE: Do not let brake fluid remain on a painted surface. Wash it off immediately.


a)FILL BRAKE RESERVOIR WITH BRAKE FLUID Fluid:SAE J1703 or FMVSS No. 116 DOT3

b)BLEED MASTER CYLINDER HINT: If the master cylinder has been disassembled or if the reservoir becomes empty, bleed the air from the master cylinder.

c)Disconnect the brake lines from the master cylinder. SST 09023-00100 Slowly depress the brake pedal and hold it.

Block off the outlet plug with your finger and release the brake pedal.
Repeat (b) and (c) 3 or 4 times.


BLEED BRAKE LINE

1. Connect the vinyl tube to the caliper or wheel cylinder bleeder plug.
2. Depress the brake pedal several times, then loosen the bleeder plug with the pedal held down.
3. At the point when fluid stops coming out, tighten the bleeder plug, then release the brake pedal. Torque: (Bleeder plug) Front brake caliper
: 8.3 Nm (85 kgf-cm, 74 inch lbs.) Rear wheel cylinder: 8.5 Nm (87 kgf-cm, 75 inch lbs.)
4. Repeat (b) and (c) until all the air in the fluid has been bled out.
5. Repeat the above procedure to bleed the air out of the brake line for each wheel.

CHECK FLUID LEVEL IN RESERVOIR Check the fluid level and add fluid if necessary. Fluid: SAE J1703 or FMVSS No. 116 DOT3

try bleeding master first it may also be damaged due to farther than normal travel when wheel cyl failed

First, before you do the bleeding, did you "open" any of the lines? Was there a caliper replaced?

If no line was opened, you do not need to bleed the brakes.

If so, please let me know and I will post the bleed procedures for you.

Why are you thinking about bleeding the brakes? Spongy brake pedal?

start by bleeding the fluid from the drivers front wheel first,till the fluid comes out. then the passenger front wheel then the rear right wheel then the rear left wheel, repeat again make sure to keep the aster cylinder full of fluid so it doesnt run dry. bleed till u get a steady stream of fluid from each of the wheels when bleeding them in the sequence ive stated.

Start from right rear, then, left rear, right front, left front. Fill master cylinder. Have helper sit in car, have helper hold brake pedal down. open bleed screw. fluid and air comes out. close screw. release brake pedal. Continue until no air comes out. Move to next wheel. Keep an eye on master cylinder fluid level after each wheel.

raise the vehicle and check the rear wheel bearings,spin the wheel while putting your hand on the rear axle you should feel the noise or check for play or movement in the rear bearing. hope this helps,please rate my fix
