If you can be sure that the master cylinder did not **** in any air during the replacement procedure then yes, you can get away with bleeding only that line. Unfortunately such a thing rarely happens. It is best to bleed the whole system. That way you can be sure that there is no air in the system and the brake fluid has been replaced to boot.Never take chances with your brakes. They're like a parachute. If it's not there when you need it, chances are you'll never need it again.

I have replaced 3 disc brake calipers on my 2001 pt cruiser. after bleeding all 4 brakes 3 times, I started the car and brake pedal goes to floor. is my brake booster shot?


Michael:

You must start bleeding the brakes at the wheel farthest from the master cylinder (usually the right rear), then the next farthest from the master cylinder, then the next, then the closest. If your master cylinder is at the left front of the car, start with the right rear, then the left rear, then the right front, then the left front. If you don't bleed the brakes in the correct order, you are just shifting the air in the lines from one line to another. Make sure that you close the bleeder before letting the brake pedal up, and the engine should not be running when you bleed the brakes... Make sure that the emergency brake is off. Make sure that the master cylinder does not run out of brake fluid at any time that you are bleeding the brakes.

WhaT is the cause of slow bleeding in brake caliper?


The front calipers are closer to the master cylinder so you are bleeding a short brake line.
The rear calipers are farther away so the lines are longer and it requires more brake fluid to flush the air out of them.

2005 Chevy Equinox left front brake caliper locks up


Your vehicle should have rear drum brakes...They have to be adjusted manually for correct adjustment...People say they self adjust but it is not good enough....by adjusting the rear it will decrease the pressure on the front and deliver equal braking...This will help eliminate caliper pressure overload....I'm not saying that is your caliper problem but it is insult to injury and will save the life of front brakes.....Now your caliper problem..FYI..A rule of thumb is anytime you change a caliper you should always replace both calipers to have identical braking pressure".The same with brake hoses and rear wheel cylinders.....The caliper that froze in the first place got hot and boiled the brake fluid and quite possibly partially collapsed the caliper brake line/hose inside as Clint and Frank stated....I am going to guess that the first caliper froze under normal conditions however got hot enough to internally damage the caliper line/hose...Then you may think of the pressure regulator being bad in which case could be a problem......So this is what you do".Since we know the left front caliper line/hose has been exposed to heat it needs to be replaced anyway...also the fluid was boiled and it needs to be changed / bled...The new caliper that froze should be ok unless it was bad off the shelf which is rare but possible."..Change the line/hose,bleed the brake system and let the mechanic test drive before you pay and leave..The mechanic will know before driving if the new caliper that froze is bad or not by rotating the wheel...This is the cheapest way...And you will know if the pressure regulator is bad or not just by bleeding system........I hope this helps....."Brooks/Metalpoet....."....

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.

Rear caliper on 2005 Ford F150 not releasing, replaced both rear calipers, now pedal goes to the floor - no brakes at all. What can/should i do?


Sounds like it still has some air in the system or a bad master cylinder. First try bleeding all air, there is definitely some air left in the lines and this is most probably causing the problem. Bled the lines at the bleeder screws on the calipers. ---------- There is air left in the brake line.Any time the brake system is opened to replace brake lines, caliper, pads etc etc.Mostly the air enters the system, and that air has to be completely bleed.Otherwise the same symptoms , what you are getting will be noticed.-------- Brakes can be bled manually, with a power bleeder, injector tool or vacuum bleeder.IIt does not make any difference which method you use as long as all the lines and components are flushed with enough fluid to remove any trapped air bubbles or air pockets.----
The most common bleeding procedure is to bleed the brake furthest from the master cylinder first, then bleed the other brake that shares the same hydraulic circuit (which may be the other rear brake on a rear-wheel drive car or truck, or the opposite front brake on a front-wheel drive car or minivan). After these have been bled, you then bleed the other brake circuit starting with the furthest brake from the master cylinder.--------- When the complete air is bleed from the line, the brake should be firm when car is on.In your case brake brake pedal is loose and goes almost to the floor when car is ON.This is due to Air in the line.Get the complete air bleed from brake line.------- This will help.Thanks.Helpmech

What special tool is need to bleed brakes on 1999 gmc sierra? Had to replace all lines due to rust. I can only get the front driver side to bleed. The brake peddle is like steeping on steel. ...


You can actually bleed each caliper at the brake line connection to the caliper...you will need someone to depress the brake pedal, or you can borrow the auto bleed brake pedal tool from your local auto parts store...sounds like you can fix this yourself...the symptom says..."air in lines"...Hope this helps.

My brakes will not get hard. The pedal goes to the floor. I just changed rear caliper and rotor on the drivers side.


DId you bleed the system after you changed the caliper? If the Master cylinder lost it's fluid while you were changing the caliper, then there is air in the system and you need to bleed the entire system. start with the REAR RIGHT, then the REAR LEFT and then the FRONT RIGHT and last the FRONT LEFT. make sure the master cylinder NEVER runs low on fluid and DO NOT re-use any fluid that you get out of the calipers.

After replacing drive side caliper, both front disk brakes, and rear drum brakes, bleed all three lines, both my front calipers lock grinding my front brakes. I am going to re-bleed my lines tomorrow but...


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.

Bleeding brakes


No need to run the engine. Start the bleed procedure from the caliper farthest from the master cylinder, and work toward it. This means bleed the passenger rear first, then the driver rear, then passenger front, then driver front. Don't stop bleeding any caliper until you get three or so consecutive streams of air-free fluid through the bleeder. Monitor the level of fluid in the cylinder, and be sure the cap is on while bleeding - only open it to add additional fluid as needed.

Unable to bleed front brakes


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
