I want to test my MC to see if its dead, I read to undue the lines and plug them up, but what should I use to plug the 2 line holes?

Do I need a special fitting?

 

I must be retarded, because I don't know what you mean by MC.

I usually use M/C to refer to a brake master cylinder when I'm in a hurry.

If you mean brake master cylinder then I don't understand the question still. You cannot really test one other than check your brake pedal to see if it sinks to the floor after you apply pressure on it for a bit.

If you pedal sinks and you do not have any leaks elsewhere in your braking system (like hoses, calipers, etc.) , then you need a new brake master cylinder - it's that simple.

 

Ok, yes sorry, brake M/C

Read my edited post above.

 

the fitting size is M10x1.0 so you need a bolt with that size pitch and some teflon tape (cuz the threads don't seal - the flare on the line seals unlike standard fittings like NPT where the taper of the threads makes a seal)

 

Hmm, I am trying to find this info, I thought I read it somewhere that if you plug up the holes and push the pedal down, if the pedal sinks your M/C is toast, but i cannot find it now for the life of me.

 

if you plug up the holes, that way you eliminate the possibility of a leak in your lines/hoses/fittings/caliper/wheel cylinders. IN other words, you are testing for leaks in your master cylinder ONLY. If you are certain there are no leaks in the lines, wheel cylinders, calipers, and fittings, then you bleed the system, and just step on the pedal... if it continues to sink with constant pressure, then you have a leak inside the M/C and you need a rebuilt one.

 

BTW, if you don't have much experience with brakes, grab the Haynes brake manual, it covers lots of stuff like this. I got one.

 

thanks b, will head to CT and buy the bolts to plug the threads and try it out

where did you find out what size fittings they were? my helms doens't specify

 

the fitting size is a standard for japanese cars. also, I needed a adapter fitting cuz the Wilwoods use standard sizes, so I needed an adapter for M10x1 to -3AN to go from the hard line to the braided lines. Gimme till after lunch, and I'll dbl check. K? BTW, there are NO standard sizes of anything on a Honda car.

 

just connect it to your booster and then press your brake pedal if it sinks then it means u need a new one.
