Brakes Front Brakes???

kendawg73 · Jan 22, 2018

So I was just looking around on LMR... I see they sell an updated front brake caliper kit (calipers and hawk pads) there the 84-86 SVO front calipers, 73mm pistons instead of the stock 60mm, selling for 229.00.

There re-manufactured.... so my ? is...

If I go out to RockAuto, I can buy re-man calipers for a 86 mustang 4cyl turbo car, that are 73mm, so then I just need to buy the pads for the same car... can get the calipers for a bout 30.xx each...

So, I assume the rotors are the same?? Is this worth it? I plan on getting replacement calipers anyway when I put the car back together (so should I get this or just the stock ones), since I've had them off, and have not idea how old they are, and I'm pretty much replacing everything else anyway on the car... I do have new ss lines all the way.

Going from the stock 60mm to 73mm calipers isnt that much of a difference. You would be better off just buying some good pads and calling it a day.

If you are looking at increasing the stopping power then you should start looking at upgrading to 5-lug

This "upgrade" isn't really one because there's no matching Master cylinder for the 73mm front/rear drum setup that keeps pedal stroke in about the same range. If you install larger diameter piston calipers and increase the fluid requirements to move the pistons a certain distance, without a corresponding MC bore size increase, all you are doing is lengthening the stroke, which can be dangerous if you are approaching bottoming out the pedal without reaching max brake threshold.

Stick with 60s. Only do 73's if you plan on the matching 54mm rears and matched MC

Additionally, you must compensate for brake bias or you'll lose overall braking performance. In other words, if you reach the limit of adhesion in your front tires even earlier than you would with stock brakes, you will not get as much braking from your rear brakes, and the overall braking performance of the car would be worse. A proportioning valve would be the most practical way to restore the proper bias.

ok, I'll stick with the stock replacements then... I do plan to convert to disc in the rear... but that's way down the road... got to get the car back together and painted first... but I did buy all new replacement stuff for the rear drum for now...

I kept the stock calipers on mine, but installed stainless caliper sleeves, better pads and new rotors. in the back I completely rebuilt the rear drums and flushed the entire system. It stops better than the two I drove brand new off the lot. I would't go road racing with this setup, but for a street car with an occasional trip to the drag strip, it works great.

Have used this set up twice now with my 89 AOD car driven daily for a few years. It really was a decent stopping car considering with just new parts and the stainless caliper sleeves. Will be a decent until you can install a proper full brake set up.

This + new rotors. World of difference compared to a worn out stock set up. Perfect for a street car.

guys- if he has an 86 then he cant use 87 and up parts on it unless he converts over to 87 and up spindles, calipers, hoses, etc.. You can't swap on 87 and up calipers onto 86 spindles and the calipers, hoses are different. You can keep the 86 struts using a spacer

to the OP, if you have an 86 and want to keep 4 lug then sorry to say but there arent a lot of performance brake upgrades for the stock setup. Get a good set of raybestos or wagner pads and a set of stainess steel hoses. RUS-693000

If you are that serious about improving your brakes, just do an SN95 spindle swap up front and do a5lug rear axle swap with a 94 to 95 rear axles and disc brakes.. you will need to upgrade the master, lines, brackets rotor, calipers etc,, and also 5 lug rims

Completely missed this was an '86

kendawg73 · Jan 30, 2018

It's not a 86, I have a '90 GT Hatch... I was just saying on Rocauto if I look up a '86 that's what list's the SVO 73mm calibers..... if I was to order them is all...

But I'm just going to buy new re-main stock '90 front calibers, I already have all new stuff for the rear, (everything, drums, springs, shoes, wheel cyl, brake cables... ect...) so I'm getting all new stuff for the front too, and I already have new SS hard lines for the car I'm putting on, and the SS braided lines for the front, and the rear connection...

I didn't know about those front calibers sleeves so I will be getting those too...

smith and wesson makes a good set of calibers

44 magnum has great stopping power.
