hello,
i recently perchased a daily driver 91 si. it has 1990 integra brakes and suspention with ground control springs/agx shocks. getting off topic but my question is my brake master cup seals are bleeding down. im getting ready to purchase a new master and was wonder in should i get an integra master? was told the one in the car is stock along with the proportioning valve? im a honda newb, my backround is toyota nissan.

thanks
tim

 

For the best results I would try to source the 1990 Integra master cylinder, booster, and 40/40 proportioning valve to match the brakes on your car. As a result this would enable the brakes to function at their best.

 

is the integra brake booster realy nessasary? what are the cons of not having it

 

well my friend told me that the integra master wont bolt up to the booster?

 

is this true?

 

You are correct
The Integra uses a master cylinder that measures 15/16"
On the other hand the civic uses one that measures 13/16"
In this case you would need to get the Integra brake booster

You will notice a stronger petal as well when it comes to stopping.
Good luck with your project!

If you need anything PM me
