Hi, i have an EG4 and i have done 1 year ago brake upgrade(dc2 front calipers, rear mg zr (=equivalent to dc2) )
Master cylinder and booster are stock ^^. Its works ok but not realy good and i have some weird isues on pedal sometimes. Pedal goes all down and stops breaking, got to leave it back and press again (not sure what is it maybe the eg4 mc sealent? )
Thinking if i shall swap to a after market master cylinder or itr. Keep my booster or swap to itr or eg6. have a felling that the best should be putting willwood mc and let eg4 booster but im just a rookie.
Any good tips of experienced addicts?

 

Where the brakes bled when you swapped them out?

All integra master cylinders are 1"...so you wouldn't need to find 1 from an itr, just so ya know.

For having stock integra front brakes, a 1" would be nice and all but not needed. A 1991 civic ex sedan master is a 15/16 and makes the pedal travel less. Feels nice and is a direct bolt on to your eg booster.

 

not all integra's have a 1" master cylinder. the integras with ABS have 1" master cylinders. the non ABS integras use a 15/16ths master cylinder. you can find that on any civic ex from 90-2000, any non abs integra from 90-2000, older preludes, and ex accords. get the brake booster and the master cylinder for best results

 

i told about the itr mc so we could avoid talking about mcs on diferent hondas.. What i would like to know is if it would work good/better a upgraded(itr or willwood) MC with stock(eg4) booster, that is if it actualy fits it, or if it is recomended to also swap it for some reason. I only imagine weight increase and may be a more sensitive pedal. as i dont like the idea to pay for something heavier and that its not realy an upgrade.. unless i am mistaken in something.

 

i used a 15/16ths mc on my stock 8" booster, even after extensive bleeding the pedal would go half way down before i would get brake engagement and then it was mushy at best. so i swapped to the matching 9" booster and pedal feel was perfect. weight difference is honestly hardly noticable, nothing enough to make a difference. I believe it is along the lines of the larger mc is moving more fluid so using the stock bb takes more effort, so upgrading the bb too balances it back out
