Is there a difference in size/pedal feel between a 99 dx bb and a 00 Si bb? Gonna do an entire brake swap this weekend and was wondering if it is worth changing the brake booster.

 

I want to say 13/16th for the Dx and 7/8 for the SI.

 

is that the brake booster assembly you are talking about or the master cylinder?

 

13/16ths for the DX and 15/16ths for the SI and 1" for the ITR if you wanna know. These are the master cylinder specs.

 

what about the booster specs?? anyone know if a integra master cyl will bolt to a sir booster???

thank you, but this i already know. i need to know BRAKE BOOSTER size difference DX and SI.

 

booster is for pedal feel. if u are going to do a brake swap just do the whole thing imo.

 

si is bigger. just swap out your old mc/bb for the si one.

 

thanks bra. this is what i wanted to know. i wanted to make sure however as i didnt wanted to replace my dx booster for the same exact one.

the si booster is getting mated to a CTR 1" mc.

 

is the CTR 1" compatible with the Si booster?

just wondering because ITR mc doesnt bolt up to an Integra booster.

 

lets hope so. to my understanding it does. the ITR mc bolts up to the SI booster with bent and flared lines of course. if not i still have the si mc.

 

Sorry about my original post, guess I didn't read correctly. I know the Integra booster is larger, but you'll need the integra booster as well. That's a sure fire way to get a bigger booster.

 

They should have the vacuum ratings stamped into the side like so:



From what little info i've gathered about this, the 290V boosters offer increased braking pressure over the others.

 

anyone know if this thing works?..if so..maybe you can use this instead.
TOPspeed power brake booster.



here's the link on ebay:

thanks JV, ima check the two and see if there is any difference between the stamping.

what car is the bb in the pic from?

 

Bottom of the picture says JDM ITR Brake Booster, but I'd be willing to bet its from a 97+. I have the brakes off of the 96, and they are almost identical to GSR's (as far as caliper and rotors).
