Brake bleeding

[Livebai8]

Hey guys, I'm going to replace my rear brake calipers. My left rear is grabbing bad. I'm also replacing the rubber brake lines on both sides. When bleeding the brakes I assume you go about it one side at a time? Or do you bleed them at the same time?

One at a time and start furthest from master culver and work your way closer.

Make sure you don’t push the pedal too far in or you may cause damage. 1/2 way should do it.

 

[Livebai8]

Thank you. I will do exactly that. I'm only doing rears so I will start with passenger rear then do the driver rear.

To keep from allowing the brake pedal to sink too far I used to have a piece of 2x4 wood that I placed under where the pedal would hit the floor. I also used to put my left foot under the pedal as well. Are you just replacing the calipers? Pads and rotors too? Resurface or replace rotors? Ceramic pads?

 

[Livebai8]

Don't know on pads and rotors just yet. Pads should be on the better side. I will try to have rotors turned before I buy any new ones but it still up in the air. I will have something there so pedal won't drop all the way down.

you dont want the master to drain when you do the swap. so take the old calipers off but leave em both hooked up put the new line and caliper in place. make sure you dont mix em up, the bleeder valve has to be on the top or highest point possible.

then swap the lines over and make sure you keep topping the master cause its gonna suck up a lot of fluid.

to bleed. the two man method, you pump the brake pedal then hold it down then the other guy cracks the bleeder on the caliper you push the pedal down more, some say dont put it to the floor, i always put it to the floor, never had a issue killing a master. then while your foot is still down helper makes the bleeder snug again, you pump the pedal 3 to 5 times he cracks the bleeder foot to floor make bleeder tight, repeat till nothing but brake fluid comes out. then do the other side. with todays brake systems you really dont need to the furthest caliper away fromt he master first any more, they dont share a line. each caliper has it own line.

or make a one man bleeder diy. with this method you can only push the pedal 1/2 way down if you want to. i made one and have it sorted on the shelf. love this thing, being i work alone a lot.

One man bleeding FTW. I bought a roll of clear tubing from Home Depot and cut a piece about 12"-18" long. It slips just snugly enough into the squirt tip of a Smartwater bottle. I used my handheld butane torch to heat and soften the end of the tubing so it'd stretch and flare to the shape of the bleeder screw head when I pressed it to it. Let it cool and it'll hold that shape and snap easily and firmly onto the bleeder screw.


I've never had a good experience with the two-person method:

Me: Ok, push the pedal.

Me: ...

Me: Are you pushing?

Helper: Oh, sorry. Didn't hear you.

Helper: *Sharply stomps pedal to floor

Me: *%$^%&*!! Easy! Slow and EASY!

Helper: Ok.

Me: You pushing?

Helper: Oh, you mean NOW?

Me: $&^*@&^#%$%&!!! No, next Hanukkah! Yes, NOW! Slow and easy!

Helper: *Slowly pushes pedal until it bottom out and sits

Me: ... Well?

Helper: I pushed it and am holding it.

Me: You gotta let me know when and what you're doing AS YOU'RE DOING IT!

Helper: Ok.

Me: Like we discussed- push slow and easy and let me know before you bottom it out and don't let up!

Helper: Ok.

Me: ... You pushing?

Helper: You didn't say "go".


...This scenario repeated four times over the course of 2.5 hours.

You two must be a riot at the dinner table. Make sure you never go skydiving with this person. Oh, and stop whispering instructions. I have a Mighty Vac that does the trick.

the guy working the bleeder valve is the boss... hes yelling, PUMP. HOLD EM. PUMP, HOLD EM. TILL HE GETS FLUID ONLY LOL

 

[Livebai8]

That's funny as shit but spot on!! I have a bleeder pump i bought for 65 VW Beetle so I could bleed those brakes myself. I'll try that first!!

Any power bleeder will work great for ya. as long as you got one, id do a flush of all old fluid while your at it. brake fluid breaks down over time. the heat from the calipers burns it up. just keep bleeding till you get nice new fluid coming out the bleeder on each caliper, do the fronts too. pedal will feel better for sure if this has never been done before.

 

[Livebai8]

Yep...you read my mind...gonna vac out all the old fluid out and bleed until it's clear all the way around.

Id suggest you gravity bleed with the lines off, till you get clean fluid, before connecting to the new calipers. No reason to flood them with any old fluid.

Id also bleed the fronts too. 5 minutes more work and another pint of fluid.

Great advice on bleeding with the lines off...thanks!

gravity takes to long for me. and once again, you need to make sure you keep the master full. or you bleeding the master cylinder now.

Cool thing about gravity, its working while you are doing something else at the same time

Distracted much!

Yo can also control the speed of the flow out of the bleeder. Does not have to be wide open.
