I have a 93 DA sedan and my **** just went kapoot. I guess using the porsche 4 POT caliper sped up the wear on my stock stuff.

Anyhow I was curious, can i use the itr booster and master cylinder with no fitment issues in the da chassis?

I can flare and make the lines thats no issue at all for me btw, im just curious if this will work in this car.

I was planning on using the ITR master cylinder and booster, then possibly one of those wilwood adjustable purportioning valves i have extra from another project. I think its necessary for me to get this because of the size of the piston and caliper i have upgraded to. With my stock stuff even in the beginning, i had alot of pedal travel before the brakes grabbed (tight upgrade well worth it with **** booster and master cyl )

I think the booster is the issue, at stops the pedal will slowly move its way towards the floor, and the fluid is still toped off, however the car revs up a little each time you step on the brakes, (a little is conciderable differance compared to my friends identical cars)

 

wait, i dont need to mess with purportioning, its still the same setup with rear disks duh, so omit the dial a valve from the senario.

 

whats really going to be the difference from your stock 15/16ths to 1"?

 

the same differance honda engineered the two peices for. The type R to my knowledge has bigger calipers. The differance probably feeds the pressure necessary for those larger peices. Now i added the larger 4 POT calipers, so surely im at the same senario IMO.

To my knowledge doesnt the ITR use a larger booster as well? Larger booster will clearly provide more pressure for braking. Its just a large vacum dighaphram, larger the part, larger the pressure, am i right or no?

 

1/16th " wont make the difference you are hoping for. all it is is the size of the piston that moves fluid through the lines.

 

Soooo...
My question is, will the ITR booster and Master cylinder work. Because the ITR uses a larger booster. The booster is what provides a good deal of the braking force with its ammount of vacum pressure it provides per push of the pedal.

Sooo.
WILL THE ITR BOOSTER AND MASTER CYLINDER FIT IN A DA CHASSIS??
I am aware I will need to flare the fittings and make lines, thats no issue, but will the focker fit in the car with no fitment issues?

I am aware the abs model has a bigger master cylinder, i am aware there is a 15/16th piston, a 13/16th piston, and a 1 inch piston in the gsr and type r. The type r uses a decently larger brake booster (the big black deal), and thats why i was curious in using it. Because clearly it was designed to provide force for the larger R calipers on both the front and rear. I need this pressure for my Porsche calipers, otherwise as i experianced before with a 15 16ths it would travel alot closer to the floor before the braking would become sufficient. Im sorry to seem like an *******, but im not debating here. I just am curious if the part will fit in the car i am using?
