bigger and better brakes

[dicain]

I have a 90 with 6" lift now,and new bigger tires are on the horizon.probly 35s. I still like stopping within half a mile /emoticons/[email protected] 2x" width="20" height="20" /> .

not sure where u can get bigger brakes, do a google search also if your running 15" rims with your 35" tires the stock brakes take up all the room in the wheels. so u will need to get like 17" rims or larger. just food for thought /emoticons/[email protected] 2x" width="20" height="20" />

Well, if you wanna spend alot of money, Brembo has a setup for the bronco....

It includes the following:

1.) 6 Piston Calipers

2.) Slotted and Drilled Oversized Rotors for maximum performance...

3.) New brackets for the calipers to fit on the stock location with the new rotors...

That's for the front, as for the rear, you might just wanna invest your money in Heavy Duty Drums, with the best brake shoes (I'd go with raybestos)

This entire kit will cost alot of money (not sure on the price), don't go to the average parts store, try a speciality race shop, they might have a setup available for the bronco....

I know what you mean as far as the stopping distance is concerned, the stock rotors look like they should belong on my thunderbird....

Check out Jeff's Bronco Graveyard. They have kits for super duty brakes up front plus rear disc conversion. As far as rear disc conversion is concerned, several companies put out kits. Some are complete and others require you to get your own calipers.

Good luck,

Hit the search button at the top of the home page and put in disk brakes somewhere there is a post of mine with a link to a good rear disk setup for around $300 . /emoticons/[email protected] 2x" width="20" height="20" />

I think this is the one BLADE262US is refering to:

I got the hydroboost system in mine and see a HUGE difference with my stock braking system. Its been on of the best investments I've ever made for her. Ask Blade, no ahrd feeling right pal? [-o<

:angry: LOL

 

[cjbronco]

>- HAHA Actually a real quick question, when you do the rear disc swap, do you not have to pump the brakes anymore? Since I put the hydroboost on, it stops so great, but the other day when it was wet i skid right through a trafic light. I was wondering is someone did the rear disc swap if it takes the "pumping" of the brakes to stop faster and on wet surfaces? Bascily does it prevent lockup?

no rear disc brakes just improve the feel of the pedal as well has more uniform brake applaction. pumping the brakes will still need to be done. if u don't have ABS. it will also allow more braking to be done in the rear so rear lock up is possible with the front as well. so a porpotion valve might be needed to correct this :blink:

When I did mine I left the rear antilocks fully intact . If you push ******* them now you feel the pedal pulsate when the antilocks kick in and the truck just stops no skidding worked out very nice . My F150 is next that damn thing wont stop for nothing . /emoticons/[email protected] 2x" width="20" height="20" />

Blade, what year is yours again? Did it come w/abs? B/c even if i did swap to a rear disc, in the wet i still need to pumo and im looking to not have to pumo that much ya kno. I guess im going to have to anyway i look at it.

Oh boy...here we go with the disk brake sh*t again! See, this time I didn't start it.

My opinion on your stopping problem is simple...quit thinking technical for a second and think physics. Did you hydroplane? Are your tires balding? Did you give yourself plenty of stopping room? How fast were you going in comparison to vehichle weight and forward inertia? You might have overlooked some of the most simple questions. Then again, maybe you already eliminated all that. But I thought I'd point it out just in case.

And Rebel,

How did you find out about Brembos for a Bronco? I've talked with everyone at Brembo that I know of and they insist they don't have an application for an 87' Bronco.

Mine is an 89 with factory rear ABS I dont have to pump the brakes at all they feel totally normal except that they actually stop the thing . I dont know why you would have to pump your brakes unless you have a little air in the lines somewhere . After 86 they dont have proportioning valves so pretty much its a straight shot to both ends the rears do go through the ABS pump . I would try to bleed your brakes again just to see doesnt take much air to make the pedal squishy . Maybe the master cylinder is leaking a bit internally not likely but possibly . /emoticons/[email protected] 2x" width="20" height="20" />

 

[BLADE262US]

After going back and reading this post again I see your having to pump that hydrocrap thing to get it to stop I would not think that was normal at all Im not sure what all is involved in that system but I would guess that something is leaking internally if you have to pump it or like I said earlier it may have air in it . Hydraulics 101 fluids do not compress so if you displace lets say 30 cc of brake fluid at the master cylinder then 30 cc of brake fluid is going to go to the caliper or wheel cylinder unless it is allowed to leak past the master cylinder pump seal then it would require pumping the pedal to acheive the pressure and displacement needed . And for your question of pumping the brakes on wet surfaces yes it stops faster and that is exactly what ABS does it measure vehicle speed through that sensor on the top of your 8.8 rear end ( 81-96 ) and send the signal to a ABS computer now lets say you slam on the brakes at 60 MPH on a non ABS vehicle this would usually result in loud screeching usually a slide ( for some reason the ass end usually wants to see whats on the passenger side ) and if it catches just right a roll over . With ABS you slam on the brakes at 60 MPH the signal to the ABS computer goes from like lets say 100 pulses per second to 0 the computer says how can this be this is not good and then tells the ABS pump to cycle the brakes which is the fast pulsating you feel in the brake pedal and if you drive an exploder it accounts for this aweful grinding noise coming from the drivers floor board any time you look at the brake pedal funny . Anyway this fast pulsing doesnt allow the rear wheels to lock which makes you stop faster due to the lack of skidding and greatly reduces the slide effect . Theres more to it than that but thats basically what happens and all faster than you can say oh shit when slamming on the brakes . I read an article once that said many a cop car were rolled trying to do there famous lock em up and slide the car around trick when the cars started coming with ABS seems if the wheels dont lock and slide at high rates of speed when the wheel is cranked they flop over . /emoticons/[email protected] 2x" width="20" height="20" />

Blade, I had to pump the brake prehydroboost. I dont have abd and now that the brakes actualy stop so well, if i press some what ahrd, the rear locks up. I had this problem with the stock unit and this one. With the hdyroboost it doesnt do it on dry surface, but the old unit did.

 

[BLADE262US]

Are you still using the original master cylinder ? If so I think I would change it . If theres no air in the system you should not have to pump it to stop . /emoticons/[email protected] 2x" width="20" height="20" />

 

[cjbronco]

Its not the original but it is a oem replacement. I didnt have to disconnect any of the brake lines for it. Just unbolted the MC from the booster.

 

[BLADE262US]

Id try bleeding it again if you have to pump them there must be air in the system or an internal leak . /emoticons/[email protected] 2x" width="20" height="20" />
