I recently swapped in a 90 Integra Vacummn Booster, Master Cylinder and portioning Valve. They are a direct bolt in. They make a Hell of a difference in stopping power. I also have CRX Si disc brakes in the rear. If you have questions please feel free to ask.

 

was it hard to take the brake booster out? dont you have to take the dash out to take the booster out, as well as the brake assembly? did you have to bend any of the brake lines to make it fit correctly?

does the pedal feel stronger now? doesnt it lock up much quicker? also, exactly which model integra did you get the parts from, and how much? thanks

 

Fill me in as well, being my booster is going.

 

Parts:
90 Acura Integra Master Cylinder and Vacuumn Booster
90 Integra 40/40 Portioning Valve

YOU DO NOT HAVE TO REMOVE THE DASH!!!!
under the dash right above brake pedal remove cotter pin and remove holding bolt
remove the four brass nuts that hold vacuumn booster on.

In engine Bay: remove the 2 10mm flare nuts with flare nut wrench. remove Booster/ master cylinder
and replace with integra, Lines WILL Bolt up no bending of the lines.

Portioning valve is loacted on the left side of the engine bay below the main fuse box. Remove the 6 10mm flare nuts, then remove 12mm holding bolts into the flare nuts. Replace with new Valve and bolt back down.

Bleed the brakes and the pedal should feel 10x stronger than before. Then your done, Take out for test drive, and enjoy. Thanks.

 

I will post pics of varies parts and how the finished parts lokk installed.

 

thanks for the info. is there any specific model integra to get it from? is it any year from 90-93 integra? are there abs and non-abs model integras?

 

did u run the rear disks for awhile w/out the upgraded MC? did it feel like the pedal had a little more travel before it engaged? i'm gettin this with my recent teg rear disk conversion and i'm trying to figure out if maybe i just need to get a bigger MC. thanks

 

is it a pain at all to remove/install both the booster and MC with the engine in there? or is there plenty-0-room?

 

Well even though i dont know about the swapping in a different booster and m/c there is plenty of room to take out the m/c and the booster with the engine in. I have removed 4 of them so far with the engines in not hard at all and yes like he said you dont have to take out the dash.......I am also interested in knowing which model you got the booster, m/c, and prop. valve out of, if it does make a difference or not??

 

I used the 90 Integra Rear and front disk, and I noticed a Big difference when i swaped them. The new Vacuum Booster is thicker that the Stock Civic/CRX. I suggest using 90 Because the 90 Integra did not come with ABS.You can swap them with the motor in. I wish i had a video of my stopping distance. When i lock them up The car nose dives hard.

 

Yeah but which model integra?

 

All they had in 90 was GS RS LS. They are all the same brake systems, just different power, spoiler, and sunroof options!

 

Sorry 3 door (Hatchback) LS = Luxury Sport. The coupe.
