Hey guys, I'm going to try and change the brake master cylinder on my brother's 95 Accord EX. I've changed mine before, but I have a CRX. Is there anything different that I have to do since this car has ABS? Do I bleed the car differently also since it has ABS? Does anyone know the steps on how to change it for this car, or is it the same as mine?
Thanks

 

Nope, you don't have to do anything different.

 

What about bleeding them? I noticed theres a bleeding nipple on the ABS system. Do I bleed that as well after I install the MC?

 

Nope. Just bleed the regular brake system as you normally would. The ABS is a seperate system with a resevoir of it's own. It won't be affected.

 

I'm not totally sure, but the ABS seems to be a totally separate fluid circuit, totally independent of the main braking hydraulic system. I bleed my brakes every couple months and have never bleed the ABS fluid. You should be able to change the M/C without touching the ABS fluid. You can bleed the ABS system if you want, but it's an involved process, having to get the actuator to pressurize the system. Just leave the ABS fluid alone unless you're throwing an ABS code.

 

Yeah, what Chiovnidca said.

PS, you should bench bleed the new M/C before putting it on.

 

What do you mean by, "bench bleed?"

 

You know? I'm not even sure myself. I think it meas filling the M/C with fluid and working it through its motions before installing it. You bleed it on your "bench." I dunno, nevermind, it's not necessary. Just install it like you did on the CRX.

 

Yea, you just bleed the air out of it before putting it on the car. It saves alot of pedal pumping. If you get good at it you can get away without bleeding the brakes at all.

 

Cool. I thought so. I've still yet to change an MC myself but at this point I think I pretty much know each and every system inside and out.

 

Go buy a bench bleed kit (some MCs come with them). It comes with two fittings that screw in where the brake lines go. There are two tubes that attach to nipples on those fittings. Then you fill the reservoir with brake fluid (use a good quality high temp fluid). You bend the tubes around until the ends are immersed in the fluid in the reservoir.Then start pumping the MC. Keep pumping until the tubes squirt pure fluid. Wait a few minutes to let the air bubbles rise and repeat until there are no air bubbles coming out of the tubes. Make sure to keep the tubes completely immersed in the brake fluid or you will just suck air back into the system. You will probably need to top off the fluid once when bench bleeding once the fluid starts to fill the hydraulic chamber. This will hopefully save you a lot of bleeding at each caliper. Good luck .
