I was wondering if there was a way to dual piston on the rear of a mav. But I also have a 93 cobra rear end in my.
Not real clear from your post what you want to do, do you have an 8.8 disc brake rearend out of 93 Cobra in your Maverick? Do you have disc brakes on the front also? What master cylinder are you going to use? Just didn't quite understand what you were asking.
it can be done. there are no stock calipers that will bolt on to the rear end. you will need to custom make mounts for the calipers. or you can see if any aftermarket kits are 2 pistons.
Yes I have a 93 disc 8.8 in the rear. I have 04 disc in the front. I was wounding if someone made a brake to some 04 dual piston calipers in the rear. So I can have dual pistons all the way around.
not trying to disuade you here and I certianly understand the more is better mentality.. but even single piston calipers should be more than adequate for rear brakes given the fact that the weakness would probably not show up until repeated stops from about 100 plus mph. You'd be far better off to sink that money into larger multiple piston setups in the front than you would for the rears. Good performance brake pads(not the ones at the autoparts stores no matter how "premium" the are said to be) will also go a long ways for the best bang for the buck too. I like hawk performance pads and use them on every vehicle I own. If you have 4 wheel factory disc setup?.. those pads all around can make you feel like you just put bigger brakes on the thing. Plus.. with improved clamping loads on the rear from that extra piston.. you might need an adjustable or rebiased proportioning valve to compensate. Which will of course negate some of the gains you just got out of that extra piston as you try to rebalance the system. Other than that.. sorry, I don't have much to offer of any specific turnkey kits. I'm positive that they're out there(try SSBC since they cover almost everything these days).. but the price will likely be too high for the small gains to be had from rear brakes. Law of diminishing returns will surely apply there when going from a disc/single to a disc/dual config. Good luck on the hunt.
I have Aerospace Components brakes on front and rear of my Maverick. It's a drag only car so I have the lightest version, and they are both 4 piston calipers. My car weighs a little over 3000lbs and I'm trying to bring it to a stop as quickly as possible from 135mph......................Aerospace does have a number 4 piston kits for the 8.8, it just depends on what you are doing with the car, road race, drag race or street...................here is their ProTouring Street setup but they also have cheaper ones. Oh yes, they also recommend Hawk pads as they come with all of their kits. http://shop.aerospacecomponents.com...dspontiachousingends-1-1-1-1-1-1-1-1-1-2.aspx
I forgot to mention that AeroSpace Components has a small master cylinder (it is actually a Lamb unit) with built in proportioning for disc's on all four corners.
^^^... cha..ching! lol maybe just turn the rears to freshenen them up and put some hawk pads on to try it for now? I think that the OP would be surprised at the results. Another possibilty is that there isn't sufficient pressure at the rears to really optimize the current setup? If you turn in hard under severe braking.. which wheels lock first and hardest? The rears should only lock when you push down the brake pedal even harder(really hard actually) after the fronts have already completely locked. Otherwise a panic stop/evasive menuever may result in the rear end kicking out unexpectedly. Everyone has a different bias preference though.. so just tune the bias to what you like really. Personally?.. I like the prop valve near the shifter so I can adjust to whatever type of driving I'm doing at the time. I tend to fiddle with things more than most though. No.. not those things. I'm definately getting older these days... sad as that may feel. lol
Just one last comment here, then I'm I drag race with a purpose built Maverick, and also road race with the SCCA. Brakes are one of the most important thing you can do for performance and safety on your car...................I don't know what kind of budget you have but brakes are not a place to skimp on $$$$$. If you are going to autocross/roadrace/drag race the car, then an adjustable proportioning valve is definately what you need because the standard 70/30 bias (for the street). There is a lot of science to putting 4whl disc brakes on a car that didn't have them before, it's not just throwing parts/pieces on and hitting the road. It depends on what size bore you have on your master cylinder as to what the bias will be without a proportioning valve, or with one for that mater. If you are using a stock Maverick master cylinder I would suggest changing it for one like the AeroSpace Components which has a built in proportioning valve specially setup for disc brakes both front and rear. If you have discs on all four corners I would take it for a drive and see which pair of wheels lock up first..................if it's the rear then you need to change master cylinder or install a proportioning valve. For a road race car you really want a bias of 50/50..................for my drag car I have a bias of 60/40.......and for a street car 70/30 should be fine depending on your driving style. Here is the kind of adjusting valve I use in the road race car.
