Default Any Downside to Removing Proportioning Valve (brakes only activate front) ?

except for more than normal nose dive when hard braking, what are the downsides to removing the proportioning valve.

if i can find a reason not to, id like to remove it and the hydraulic lines going to the rear drums. so when i press the brakes it will only use the fronts.

anyone have any insight?

wow. aside from ruining your brake balance and overloading your front brakes, making your car dangerous to drive, go ahead

but in all seriousness, don't ditch your rear brekes

Yeah, the rear brakes do A LOT more than you think. Go buy a rear disc conversion. Then you have the added performance and the advantage of good looking rear brakes.

Think about when you might do some hard-braking on a curve/turn. The rear (with the wheels being free) may want to slide ahead of the front. Especially on wet raods. Also, it's less braking power. I mean, normally even with rear drums, that's sometimes not even enough braking power. You may not be modifying your prop' valve, but it's not something that should ever be messed with in that sense. Just be on the safe side.

maby i should have said this from the beginning but on the front are 11 inch rotors...

main reason i want to ditch it is to simplify things, and remove the hydro lines off the firewall.

didn't think they did as much as you guys say they do.

Sorry, but no the **** they don't. I don't have my rear brakes hooked up on my heavy-*** Prelude and for daily driving I can't even tell the difference. I had to slam on the brakes in some gravel the other day to not hit some lady and I stopped fine.

When you stop, the weight of the car goes to the front brakes anyway, the rear only do like 20-30% of the braking.

You'll be OK disconnecting them, but it's not the best/safest idea.

And how long have you had this done, and what do you have to support your scientific claims of how much braking each set does?

It's been about a year now with not a single problem.

I don't claim to know the exact percentages, but that is a rough guess from the many times I've read about this subject. If you need scientific documents to believe that a cars weight goes to the front when braking, then arguing with you will probably be pretty pointless.

I think its 95% front 5% rear as far as braking power/use with rear drums. Notice you can go 3, 4, 5 times changing youre front pads without having to change the shoes once.

so based on what you guys are saying, im starting to lean towards removing the hydro lines for the drums...

i already have SS brake lines, larger calipers, 11 inch roters..

As long as you dont live in New England, I could care less, go for it. No one really needs rear brakes anyways, so you should be 100% fine.

I think it's a horrible idea to remove the ability to use your rear brakes. They aern't there for fun.

He doesn't want you driving near him with no rear brakes. And neither do I.

Your rear wheels may not do much stopping, but they do produce drag that keeps ALL of the weight from diving to the front.

As long as you don't have to do any evasive maneuvering probably not gonna hurt much. However you drive a FWD car, and in more extreme driving circumstances you're asking your front wheels to do 100% of the braking and 100% of the steering, that sounds kinda dumb.

It's your car though, and I don't mind if you live near me, if we ever got in a wreck and the cops figure out you removed your brakes, they won't even bother wondering who's at fault.

A+++, 100% accident liability. Where DO you live by the way, skriblah? If any of us need a new paint job, or a body panel that we dont quite have the money to replace ourselves?

Hawkze, how about you? Your another free insurance ride, where do you reside?

ooh ooh me me me me me....

please be sure to hit the rear passenger section of my car.

thanks.

On a serious note, i wouldnt remove the brakes....they sure as hell didn't put rear drums on cars for their fantastic looks.

Just doesn't sound like a good idea to me, removing part of a safety feature on your car, no matter what percentage of stopping power it provides.

especially if its only to make your engine bay slightly better looking. the cool part of mechanical things are the pieces/parts that make them work. im sure there is a better way of cleaning up the engine bay, and something better you can do with your time.

because you will still have the ugly *** drum brakes hanging out back there.

word!!

what if you did take off your rear brakes? then you would only have 2. what if one of your front brakes f'd up? then you'd have 1 brake to stop with.

If honda thought that rear brakes didn't do much or were not needed. They would not put them on. Keep them hooked up, end of story.

I'm just astonished that you ever even entertained it in the first place.
