It is normal to have no brake pressure for the first 1-2 pumps after replacing brake pads, but I assume you are past that. You should not normally have to bleed the brakes after doing only that.

When you retracted the pistons back into the calipers to allow the new pads to be fitted, was there any leakage noted? Were the pistons out of the caliper pots far enough to let any air in? What was the brake pedal like before this job? Was it spongy or low? The air may already have been there.

Check the caliper/pad assembly to see if everything is in place OK, and if so you will have to have the system pressure bled. If the car has ABS brakes you will usually have to pressure bleed them anyway, as the old 2 person method will often not get all the air out.

Do you have an electronic brake pressure pump for brake assist that you may want to make sure works properly. When turning ignition on, you should hear the motor run, also when you press the brake pedal.

Rear passenger brake dosen't work


Are there two brake fluid reservoirs? And are both full? This would be a split-diagonal brake system-front driver and rear passenger are one brake system. Front passenger and rear driver are the other system. You have the one system working-the front passenger and rear driver side works. You will have to keep bleeding the rear passenger side and the front driver side-always start farthest from the master cylinder, but if that wheel just won't bleed air out, make sure the driver front is working and bleeds good. If all else fails, there are pressure bleeder kits available, I don't know the cost, but they work great. They are also a one man bleeding job, as I understand.

1992 Suzuki sidekick has front brakes locking up after a short drive. Problem started after right front caliper piston was frozen and left front caliper slides were frozen. Replaced right front caliper and...


stop and do not drive, get a brake man, in the loop, danger !


this is cause by the MC, the master cylinder, no ABS in 92
not replacing relic calipers in pairs is dumb, sorry risking life and limb using old 20 year old calipers is not bright. a fact, not opinion.
are both caliper locking, at ONCE?
that is the key question .
reasons. (answer for BOTH clipers locking at once)
1: bad calipers ,no piston lasts for 21 years, ever. (relic)
2: the MC piston is not retraced,

#2 is caused for 2 or 3 reasons,,,,
2a; brake pedal adjusted such that the factory play behind piston rod is not zero or minus, causing the MC to lock hydraulically.
2b; the booster was changed and the PP mechanic (weak) did not
RTM , they did not adjust the new booster, calibration ring stated in the FSM.
3: if one caliper (good) locks the rubber flex line is breaking down
inside and is clogged. 21 year old lines are not good to trust.
not life and limb or mine when you hit me...
that too, is fact.

the guide pins must be free, and antisieze lubed or with special
99cent OTC brake grease (very high temp rated,) ask.
the pistons rust. DOT3/4 is hygroscopic and will rust in 21 years.
not a guess. fact.
One other point, 21 year old caliper seals will no longer have
stiction, they fail to retract the piston and the pad drag. wasting fuel and pads. new seals. better, newly rebuilt Raybestos calipers
will make them safe.
fixing brakes in a serial fashion is asking for trouble.
do not cheap out on brakes.

Replacing caliper on 2002 dodge neon


The first thing is to make sure the caliper piston is all the way in, the caliper then slides over the brake pads and bolts on, make sure you have the correct caliper on the right side, the way to know this is when caliper is on the little bleeder screw should be on the top, if it is on the bottom then wrong caliper, try the other one,

After caliper is on you will then need to bleed the brake system,
This all depends on what happened, if the brake fluid did not all leak out and caliper was just bad then before removing brake hose off old caliper pinch rubber brake line with a pair of needle nose grips or there is a line crip tool that crips hose to avoid fluid from leaking out. this makes bleeding easier , other wise you will need to make sure fluid is full and start at the right rear wheel bleeding and move to left rear then right frt and last left front, you will need to keep an eye on the level of brake fluid and add as need to keep it from going empty,
you will need some one to pump and hold brake while you bleed them, pump pedal three times and hold down while you open bleeder screw, this is to be done to every wheel about four to five time to make sure all air is out . good day. note if pedal feels low bleed again wont hurt anything just a little more fluid lost.

All of a sudden i have spongy brakes on my 92 f 250. changed master cyl and booster. and rubber brake hoses. still spongy and nothing is leaking.brakes went from being good to spongy in one...


Check the rear wheel cylinders? Was anything leaking at the master cylinder? Does it have ABS?
Check the front caliper slides are free. Check the front caliper pistons for leaks as well. This is all assuming you bled the brakes(all 4 wheels) properly after all that replacement! You're getting air from somewhere for sure or if it has ABS, the pump may have a problem.

How to bleed brakes on 1997 Saturn


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.

How to bleed brakes on 2002 toyota sienna


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

hi from the uk have had this problem on a customers car b4 who had replaced frot calipers and pads and pedal went to floor on inspection of caliper i found that the steel spring clip that fits into two holes in the front face of caliper and must also locate behind the caliper carrierbehind two lugs was fitted incorrectly it had been fitted behind the outer pad resulting in when brake pedal off ?the caliper being floating type as it is known because it is fixed by two screw pins/bolts and moves on these pins/bolts as pads wear ? what happens is the spring fitted wrongly ? actually pushes against the outer pad and as a result the caliper piston is pushed back into its cylinder slightly as it moves on the locating pins/bolts resulting in pedal going to floor on 1st application but if pumped ? some brake pedal force is felt but is lost again when pedal released ? so try this ? remove the steel clips from both front calipers that retain caliper to carriers then press brake/pump pedal ? if as suggested above works? your pedal should pump up and remain ok when you release and still be firm when re applied ? all above is what i found on ford ford but many other models use similar calipers and spring locating recheck how this spring should locate hope this helps ? good luck

Pistons in both front calipers stay out, both calipers replaced


You may have a leak in the booster or master cylinder. You can put a pressure tester on the system to test for leaks. It does sound like you have an air leak.
You can try to bleed the master cylinder, then slave cylinder, then brake lines.

No brakes after changing brake caliper & bleeding system


Sounds like you still have air in your brake lines. Make sure all your brake lines are tight. Then bleed again. Bleed the trouble side first, meaning right side, then go to front left, back left then back right, make sure that your brake fluid is also full
