FORD EXPLORER WHEEL PROBLEM

1999 Ford Explorer

Tried bleeding brakes numerous times, but there is still air in the line. There are no leaks in the hoses. Could it be the brake flex hose?

WITHOUT ACTUALLY SEEING YOU IN ACTION--IT'S HARD TO KNOW WHAT YOU ARE DOING

IF YOU HAVE DRUM BRAKES---THEY WILL NEED TO BE ADJUSTED TO GET THE BEST PEDAL

(SOME OF THIS WAS FROM ANOTHER ANSWER I GAVE, I WENT BACK AND COPIED IT)

ADJUST SHOES OUTWARD, CLOSE TO THE DRUMS (THEY SHOULD SELF-ADJUST, BUT WHEN THEY GET DIRTY OR WORN, THEY DON'T WORK RIGHT, AND DON'T ADJUST)

I USE A BRAKE SPOON. I "ADJUST" THE STAR WHEEL UNTIL THEY JUST START TO MAKE A SCUFFING SOUND, WHILE YOU CONTINUOUSLY SPIN THE TIRES ***NOT UNTIL THEY DRAG***----IF YOU GO TOO FAR, NORMALLY YOU HAVE TO CRAM A THIN SCREWDRIVER IN BESIDE THE STAR WHEEL AND PUSH THE RATCHET ARM OFF OF THE STAR WHEEL SO YOU CAN "UNLOCK IT" AND TURN THE WHEEL THE OTHER DIRECTION.

"TO ADJUST SHOES OUT/ SPREAD THEM APART"----"NORMALLY YOU INSERT THE BRAKE SPOON IN THE HOLE WITH "YOUR END/ HANDLE END", UP IN THE AIR---THE TIP WILL BE DIGGING IN AT THE BOTTOM OF THE WHEEL (THIS MIGHT BE JUST OPPOSITE ON A DIFFERENT VEHICLE)....PULL "YOUR END" DOWNWARD (LEVERING OFF OF THE BOTTOM OF THE OVAL HOLE) YOU MAY FEEL/ HEAR THE RATCHET ACTION....BOTH SIDES ARE "MIRROR IMAGES" OF EACH OTHER....THE SAME ACTIONS WILL APPLY FOR THE OTHER WHEEL

MAYBE THE EZist THINK TO DO IS ADJUST THE STAR WHEEL A FEW CLICKS AT A TIME (SPREADING THE SHOES OUTWARD)

THEN PUT THE DRUM ON FULLY---HOLDING IT ON FLAT WITH ONE HAND AND THEN ROTATE THE DRUM CW AND CCW LISTENING FOR A SCUFF

PULL IT BACK OFF AND ADJUST SOME MORE----PUT THE DRUM BACK ON---REPEAT THE PROCESS

YOU DO NOT WANT THE DRUM TO DRAG OR NOT MOVE....BACK OFF SOME IF YOU WENT TOO FAR

WHEN IT SCUFFS---PUT IT ON PERMANENTLY

GO DO THE OTHER SIDE!

My Bench bleeding ain't on the bench...it's on the vehicle!

Much EZer that way!

This can be done on the vehicle (my preference) using two people, one pumping and one monitoring the Master Cylinder.

I wrap string loops around the little hoses and tie a knot, as to keep the tubes from blowing off of the plastic adapters.

I take it one step further, by squeezing the little hoses with my fingers (as if I were a check valve) The VERY SLOW PUMPING OF THE PEDAL will push the fluid into the reservoir, SCOOTING BY MY PINCHING, but the pinch will not allow it TO S.UCK AIR BACK, as you see in the beginning of this video....My way makes things faster, but if you did not tie the hoses to the adapters--THEY WILL BLOW LOOSE (lots of adjectives will be bust loose out of your mouth!)

This is very similar to my way

xbleeding

This is the basic bleeding procedure I use:

KEEP FLUID IN THE RESERVOIR AT ALL TIMES/ CONSTANTLY CHECKING!

START WITH FURTHEST OUT WHEEL CYLINDER, FROM THE MASTER CYLINDER, WORKING TO THE CLOSEST (RR, LR, RF, LF)

2 PEOPLE, ONE PUMPING, OTHER BLEEDING AND REFILLING

#1 man is the Bleeder

#2 man is the Pump Man

1-MAN BREAKS BLEEDER LOOSE-SNUGS IT BACK YELLS, "PUMP IT UP"

2 MAN-PUMPS 6-8 TIMES (YELLS "PUMPING") THEN HOLDS PEDAL--YELLS, "HOLDING"

1-MAN CRACKS BLEEDER...AIR/ FLUID SPURTS OUT

2-MAN YELL, "FLOOR", JUST BEFORE THE PEDAL, ACTUALLY HITS THE FLOOR

1-MAN TIGHTENS THE BLEEDER....WHILE IT IS STILL SPURTING OUT (NOT AFTER IT STOPS...OR IT WILL SUCK AIR BACK IN).....THEN YELLS, "OKAY---PUMP IT UP"

PROCESS STARTS OVER UNTIL YOU ARE SATISFIED, WITH EACH WHEEL

THIS DOES NOT MATTER WHETHER THEY ARE DRUM BRAKES OR DISC.

ON DRUM BRAKES:

YOU SHOULD ALREADY HAVE THE SELF-ADJUSTERS PUSHING THE SHOES CLOSE TO THE DRUMS, SHOES SLIGHTLY TOUCHING THE DRUMS , BEFORE YOU DO THE BLEEDING PROCEDURE.....THIS WILL KEEP YOU PEDAL AT THE TOP AND TIGHT.

I PREFER THIS OVER USING THE ONE MAN, HOSE AND CUP, METHOD WHERE YOU SUBMERGE THE HOSE AND PUMP....TO ME THIS IS FASTER AND MUCH EZer.

IS THIS THE WAY YOU APPROACHED YOURS?

SOMETIMES A MASTER CYLINDER WILL ALLOW FLUID TO SLIP PAST IT'S O-RINGS---(BAD MASTER CYLINDER).....OFTEN THIS IS CALLED AN INTERNAL LEAKAS NO FLUID IS LOST---IT JUST DON'T GET "PUSHED" AS IT SHOULD

IF YOU THINK YOU HAVE A HOLE SOMEWHERE---99% OF THE TIME IT WILL BE LEAKING----SEEN ANY BRAKE JUICE ANYWHERE?

KEEP ME POSTED ON HOW IT'S GOING
