Thread: Change caliper without having to bleed brakes?

You're right the time to do it isn't a major issue but I'd rather not have to bleed the system if I don't have to. The biggest factor against having to bleed the whole system is the rusted bleeders on the front. The front calipers are only 2 years old but North East weather makes things rust quickly!

You don't need permission to do it. Its your ride. Just realize its totally impossible to have good working brakes if you don't bleed them. I promise you no matter what scenario you invent nobody is going to say otherwise.

your bleeders wont snap. just take a socket and only break them free all around then its set for when you want to bleed them.

i did that on my 240 and my calipers were sitting outside exposed to every type of weather imaginable lol

and get new bleeders while youre at it.

Your better off to bleed them man. Last thing you want is to have air in your brake lines. Even if you clamp the lines your still gonna either A. lose brake fluid or B. Get air in your lines. Bleeding brakes takes all but 5 mins anyways, I don't see why it's that big of a deal

I got some speed bleeders from summit for fairly cheap. Well worth the investment.

Don't clamp the lines. Throw a phone book onto the brake pedal before you disconnect the line. When you unbolt the hose you will have a little bit of fluid come out, but it won't keep dripping as long as the brake pedal is slightly applied.

Once you have the old one off. Hook up the new one and open the bleeder. Then bring the brake pedal back up to the very top. This will allow fluid to flow into the caliper. Give it ten minutes or so and keep the brake reservoir filled up with fluid. When you get a good steady flow of brake fluid out of the bleeder, lock it down.

Done.

This is gravity bleeding. No pumping required. Maybe it will save you some time.

You can change the rear calipers without having to bleed the fronts if you do it quick enough and yea clamp off the lines to the rear ..... But you will need to bleed the rears !! There is air in the new calipers so you will have to do a little bleeding on the rears to get all the air out !! The above gravity method will help , but you will still want to do a couple pumps to get all the air out ... One Person bottle bleed should do the trick and only take a couple minutes and you can do it yourself !!

you have to at least bleed that one line. I did that on my right side caliper. Oh BTW, it is sometimes sticking, my new one. Check than damn parking brake. If it is too tight, it can be a problem

You will only have to bleed more than that line if you lose a lot of fluid (enough to drop the MC level below its line outlet point). As long as you stay above that level, all of the other lines will be fine. Keep an eye on it, change the caliper, pump the brakes a few times to bleed and you'll be done.
