Replacement of on front caliper

On replacing one front brake caliper is it necessary to bleed the rear drum brakes or can I bleed just the front brakes? Thanks for the help. Looked for similar postings first and nothing matches my question. John D.

Re: Replacement of on front caliper

if you have a 2 compartment master cylinder you can just bleed either or

Re: Replacement of on front caliper

Not sure if its what others would do but I would change the caliper, pop the master cylinder cap, check the fluid level, gravity bleed the new caliper until it drips, lock it all up, then bleed it (with bake pedal), recheck the fluid level and you should be good to go. you shouldn't need to bleed the rears but.......all scenarios are different so check that you have a good pedal before you drive off into the sunset.

Oh, don't forget to adjust your rear brake too.

Re: Replacement of on front caliper

As noted if you have a dual MC, yes

with that said if the brake fluid is a few years old I would flush/bleed all 4 corners

Also make sure your other caliper works like the "new" one....typically they are rebuilt or replaced as pairs

and since you are opening up the hydraulics...a good time to replace the soft lines if they need it

This is what I do as well except I clamp of the brake line going to the caliper, replace it, bleed it via brake pedal, then I top off the fluid. I never open the reservoir until after everything id one and sealed to add fluid.

Like mentioned in post #4 now is the time to replace the rubber hoses. At least the "2" calaper hoses. Many calaper s have been replaced because of a bad hose not detected. Clamping an old line can also cause the inner tube of the line tho collapse. Causing s sticky calaper feel. Some swear by it, but I'm not s big fan of the gravity bleed method. I use a 12 year old daughter method. Works every time.

IMHO the gravity bleed is just the beginning. After it's gravity bled other methods need to used to complete the bleeding to get a good pedal.

Next year you'll have to borrow someone else's 12 y.o. daughter or find a "new" method.

Re: Replacement of on front caliper

Not a fan of clamping brake hoses. Changing the hoses is always a good idea.

I advise people to gravity bleed first because if you don't know how to properly "pump" a pedal (12 year or older) you can pop the master cylinder. If you don,t know what popping a master means your a lucky man. Fellow Tech's can explain....Lol

You don't have to use much force to clamp a rubber hose with a pair of needle nose vice grips and as long as you do it gently it won't hurt anything. Sometime you gotta do what you gotta do to get the job done especially when you are by yourself.

Been ASE certified since the 80's and had my own single mechanic 4 bay shop for almost 30 years. Never heard of, or had a master cylinder pop. I have clamped the lines with a specific hose clamp. It can be done for sure. But if it's an old hose it's not worth the risk. I would rather let it drip and top off the MC than clamp an old hose. My customers know that I'm the mechanic, and to expect a quality job. This means new lines on every new caliper, and new rotors on every brake job. You can teach a monkey how to pump brakes for bleeding. The key is to not pump them like a gorilla.

Re: Replacement of on front caliper

a sandwich bag and a wire tie works wonders to catch the drips if you are concerned. just place a rag under the line when removing the bag
never pinched a line
never had to

Re: Replacement of on front caliper

Hey Keith, Agreed when working with newer cars vs clamping. I have and have used clamps on brake hoses. I guess I should have mentioned when working on these old cars. You,ve never had or heard of someone bottoming out an old or new master while bleeding bakes, damaging the cups and ruining a master?

Never heard of anyone actually doing it no. The proper way to even bench bleed, was to never bottom out the master cylinder. I guess some people do, and that's what you are talking about. I have a small shop, and only turn out around 300 brake jobs year. About 25% of them being muscle cars. I don't claim to have done everything, or see everything, just not a blown master cylinder.

Re: Replacement of on front caliper

As long as you're bleeding I would suggest a set of braided hoses. They give the brakes a really nice pedal feel.
