about to do a gsr brake swap and was wondering if changing the master cylinder is necessary.......if so how hard is it to change the mc ? any specific tools that would be needed to take it out. i guess this is a newbie question but any help would be great.

i know that you need to change the proportioning vavle when upgrading the brakes.

but i was just wondering if it needs to be done when swapping out the brakes
thanks

 

no takers

 

i just did the same swap and was wondering the same thing

 

Well first what kind of car are you doing the swap on?? You may have the same size M/C. And if not its not very hard to change them out. 2 nuts 2 lines and thats it. The hardest part will be bench bleeding the new M/C.

If you just did the same swap wouldnt you know how hard it was??

I think he meant he did the brake swap, and was wondering how hard the MC swap was.

I did Integra brakes upgrades on a 00 EX and a 92 VX, and niether need the new MC or prop. valve, they will still stop just fine. However, the VX does not have as good a pedal feel as the EX did after the swap, so perhaps the new MC and valve would do more for it.

As far as how hard it is to do, I was wondering what bench bleeding actually is. Everyone tosses it around whenever you mention MC swaps, but I am starting to wonder how many are just regurgitating info and if they actually know what it is.

Well first a proportioning vavle wouldnt do anything for brake feel it only controls how much fluid goes to the front and rear brakes. I would recommend changing it to the one from the car with the 4 wheel disc brakes.

Bench bleeding is basically how it sounds. You bleed the M/C while its out of the car. For the most part when you buy a M/C it will come with a bench bleeding kit which will include like plastic nipples to screw in where the lines go and also some hoses to go from the nipples and into the M/C resovoir. After You have it all together you fill the resovoir up with fluid and then you push in the acutator on the back of the M/C to bleed out all of the air bubbles you will see the air bubbles going from the tubes to the resovoir. I suggest putting the M/C in a vice to do this I did it in my lap and it was a big pita!! First keeping it level so fluid wouldnt spill out and second trying to push in the actuator smoothly while its on your lap isnt that fun either.

 

Thanks for the info, I had been wondering about that for a while, and I may be getting a new MC in the near future.

BTW, good point on the prop. valve, I did not mean to suggest that the prop. valve would improve brake feel (my fault for bad wording). I was just thinking the two upgrades would benefit the VX more than they might have for the EX, but thanks for the correction.

NP....I wasnt trying to say that you were saying that it would help brake feel I was just letting everyone know so in case that they didnt know that it wouldnt help.
Oh and your EX M/C is probably a 15/16th and the VX is a 13/16th which would make the brakes feel different since there isnt the same amount of pressure there.

 

oh yeah, well i have a 92 civic 4 dr dx, it has rear drums.....so i had read that its good to change out the prop. vavle cuz i have the drums in the rear and the disc they need more fluid. (is this true ?)
and i just never knew what all you had to do to take out the mc so thats why i was wondering......so i guess if it only helps pedal feel then i might try it first without the mc and see whats it like. but i was planning on changing out the prop valve anyway.

thanks for the resonse guys....

 

Well the rear disc's dont need mroe fluid per say BUT it would just help out with braking you may not even change it and it could be just fine but if you look at a typical disc/drum set up for the most part is 70% front and 30% rear something with all 4 disc brakes might be something like 60% front and 40% rear. So with that kind of difference it may not even be noticable? I have also heard that one of the integra's have a 50/50 prop valve dont know how true it is and really dont see the advantage either?

Yup, that is exactly the case. That's why this time around (with the VX)I am actually considering the new MC. Thanks for the help.

 

Instead of bench bleeding I install the mc and bleed it with the bleed kit with a friend pumping the brake pedal. Then I install the lines.

Thats not a bad way of doing it as long as you have someone to help you out doing it. I have never had a problem bench bleeding myself though.

 

The only reason you would change the prop valve is if you did a rear disc swap. Other than that there is no point. Basically the drum brake prop valve doesn't send enough fluid to the rear for disc brakes. Thats why people put in Integra prop valves.
