pedal ratio

Hey guys I'm trying to delete my abs unit and brake boosters. I've talked to Wilwood about using their kit and they recommend a 6 to 1 pedal ratio instead of the stock ratio which I believe is 3.3. Does anyone know how to convert the stock ratio to make it a 6 to 1 ratio? Thanks

Re: pedal ratio

I can tell you that the pivot point of your brake pedal will need to change. That will give you more leverage on the master cylinder, which will put more pressure on your calipers, pads, and rotors. Are you going with bigger rotors and calipers? If not, then the effort and work you put into changing/modifying the brake pedal assy might not be worth the Time/money.

Re: pedal ratio

Correct, it's all about the pivot point. Read this:

Brake Pedal Ratios

You'll need to move the pivot point up the pedal to get a lower ratio. This could be much easier said than done. Take some measurements of the existing pedal though, I suspect the stock ratio is much closer to 6:1 than 3.3:1, the pivot point is right near the top.

Re: pedal ratio

Well what is going on is my brake system locks up and my pedal stays extremely stiff. We disconnected the abs unit to see if that was the problem and had my rotors replaced since they got warped from heat from the calipers being stuck. That didn't help at all and a few days later the brakes locked up again on me. The car isn't my daily either. I got a new abs unit to try from a parts car I got to test to see if the actual abs unit causing the issue rather then just being disconnected. I'm not going for looks or extra performance, I just want my car to work again and be safe. If it is a brake booster issue I'd rather delete it and abs.

Re: pedal ratio

Did you fix the sticking calipers?

A very common Honda issue. Especially on ones that sit...even worse when the e brake is left on a lot.
I gotta do both my rear calipers. I think Wings had some nice rotors get ruined from that. He used remanufactured from Honda if memory serves...

^^^ Hit this issue right on the head... It's MOST LIKELY your calipers. Like 99%. It could also be the rubber brake hose from the hard line to the caliper has swollen shut. I has this happen on 2 different cars, but only those 2 times.

The neoprene pistons in the calipers have a tendency to swell and quit moving. Sometimes it's just the brake fluid that gums up in there. Some MFGs and aftermarket Co's started making metal pistons as replacements. It may be cheaper to rebuild the calipers yourself, if you have the experience, but if you don't have that or the time, the easier solution is to replace the calipers. It looks like AZ has the rebuild kits as well as replacement calipers. www.RockAuto.comis another resource for replacements.

Is the "clogged" brake hoses also a common issue on the Preludes?

My issue was on GM cars. And the Neoprene caliper pistons that locked up on me were on an 89 Ford Escort.

Re: pedal ratio

Apparently clogged hoses on disc brakes are like head colds in January...don't matter where ya live, what ya drive or who your daddy is...you're likely to have one sooner or later.

When studying brake re-hab that was #1 issue on every site I lurked.

Re: pedal ratio

Abs unit some how became defective. Replaced it with one off my parts car and it's good now. I appreciate the help guys. One thing I don't get is how the abs unit would just suddenly stop working with no prior symptoms and never threw a abs light
