What the hell is going on here, why are people still confused? If anyone is confused on any of this please ask a SPECIFIC question on what your confused about.

I think you mean BRAKE

yeah...spelling police here... :p

I'll wait for blinx to chime in here...as it seems the prop valve on 6th gen hatches in the USDM did not vary and were all of the 4040 variety.

Otherwise, get one from a 99/00 Si/SiR(if you're Canadian)
Im in no way Canadian (thank God) but i do have a Canadian 96 Honda HB CX ( God hates me...)... Why are they saying canadian cars need to swap their PV, also, Is the MC different on canadian cars?

Whats wrong with being Canadian? There is no room for racism on this board, joking or otherwise. Please refrain from making such comments in the future.

first off:

96-00 EX SI have the big front calipers
96-00 (CX, DX, HX) have the small front calipers
96-00 EX has drums in the rear
96-00 (CX, DX, HX) have drums in the rear
99-00 SI has disk brakes in the rear


the SI shares the prop valve with the hatches (or the DX,HX coupe) because of the smaller (than the EX,SI and some 4 door models depending on country) front brakes. the smaller piston in the smaller calipers needs only a lil more fluid movement than the rear drums in order to work correctly. it just so happens that the bigger front calipers combined with the smaller (than the front ones) rear calipers require the same fluid movement in proportion to each other and thus the same proportion valve.

now everyone thinks its only the hatches because all of the hatches were CX or DX. but if you find a DX or HX coupe it WILL have the SI-type prop valve.

any questions?

It's Americans like yourself that makes the rest of the world view your nation as a whole bunch of asses.

Luckily, I have very good American friends and can distinguish the difference.

This is the 40/40 prop valve which we had to install on several brake conversions. The civic's in the UK that dont have rear disk on them from factory come with a differant valve on them and when you convert to rear disk it just dosn't have the pressure for the rears so the pedal has a long travel before you get brake preasure.

That picture is what is used on tegs and 92-95 civics, VERY different that the 96-00 civic prop valve.

Also thats a very bold statement your making, it would be nice if you listed exactly what cars its applying too because it absolutely does NOT hold true to the 96-00 civics using the smaller front discs with drum rears.

Blinx. The cars have been EJ8's and EJ9's. All have had the smaller prop valve like the one that comes on the USA SI or the UK VTI with 4 wheel disk. These have the 242mm front disks. After the conversion is done brakes are bleed they work fine but there is alot of pedal travel before the come on. First time thought it was just air. Rebleed them over and over. Still the problem. Changed the prop valve to one of these and problem was gone. Pedal feel is just right. Moves a little and you have brakes.

interesting, what size are your master cylinders, maybe that could be why, or like your saying maybe UK use different prop valve all together :confused:

Hmm, are 94 integra gsr front brakes bigger than a 96-00 dx hatch?
