S10 Brake Upgrade - Documented

As promised, I documented swapping my 79+ belltech drop spindles to the S10 Blazer dual piston setup. Don't forget, you will need to align your car after doing this (mine was toed in .5" on both sides afterwards)

The first step was to compress the spring with a floor jack and remove the old spindle/hub assembly in one piece after disconnecting the brake line. Note that I have -AN flare brake line adapters which are not factory.


One thing I had to do that most of you won't was installing my ARP wheel studs into the hubs. I just threw them in the drill press to enlarge the holes with a silver endeming bit, then i used an old 7/16 lug nut with some washers on the impact gun to seat the knurls.


Next, I put the new spindle on (don't do the final torque of the balljoint nuts and insert cotter pins until the car is on the ground). I put some anti seize on the surface where the hub will go because it was pretty corroded when I diassembled everything for blasting & coating.



Next, I applied blue loctite to the hub bolts, and put them in from the back so I could hang the dust shield on.


Next, the hub can go on. Note the orientation of the abs sensor to match the opening in the dust shield.
I torqued the bolts to 60 ft/lb (not sure what they should be but this seemed right for the bolt size :) )


This is how I took care of the pesky ABS sensors (they are fairly interchangeable on GM cars too, so if you have another GM, keep them as spares!)


Next, I freshened the brake caliper mounts with new bushings and dust boots along with some
Permatex high temp ceramic brake lube on everything. I got the parts off the shelf from Advance Auto parts.


Now, The rotor can slide on and the caliper bracket can be bolted up from the back side.


Install the new anti rattle clips on your new pads, and throw them in. I chose Thermoquiet Ceramic pads from Advance because they will probably last forever with the mileage this thing sees.


Now I could compress the caliper pistons fully, and install them. There should be plenty of clearance between the caliper and new pads so it drops right on. One thing to note is that the caliper bolts may be tight due to the new bushings/boots that were installed in the brackets. This is normal, and I used a rubber mallet to seat the bushings further so I could get the thread started on the bolt/caliper.


The banjo bolts are the same size on the old calipers as the S10 calipers. Now, I have stainless braided hoses and don't know what factory g-body hoses are like but they must be similar if mine work, so you should be able to re-use yours also. I have a strange manual master cylinder and these brakes work great and grab tight. I also used them with my line-loc, and they grab tight!

And that's all she wrote! I read these weigh about 4lbs heaver per side than the factory brakes. That's ok with me because the braking surface area is MUCH greater due to the size of the pads and the .5" larger rotors. I'll do the percentage increase calculations if I have time, but it's not hard to see by looking at them.


My main reason for doing this swap was because I wanted to get rid of the drop spindles. This was my goal because I am now able do drop my coil over springs way down and regain my long lost front suspension travel. Instead of putting the money into just spindles, I figured I would do the whole swap and get better brakes at the same time. Plus, I think there is no need for drag racing only brakes since I want this car back on the street eventually.

Are those sealed hubs? Are they replaced as a unit rather than to periodically repack bearings and reset preload on the bearings?

Is there any difference in track width when using these spindles/hubs?

The hubs are sealed units but I didn't think that would be an issue for me.I got a 90 day warranty on everything and dont think my use will wear them out.

Also, I am running 15'' wheels

Hey, when I was doing my research, I kept reading that you may be able to use the 4wd spindles but I never saw a straight answer. I think i looked up the ball joints and the 4wd ones may have had a different part #. They also might have a wider track width on the 4wd setup, but I'm not positive.

is unfortunately the 4wd unit is wider and IIRC the ball joints are different as well. This can all be overcome but that kind of defeats the purpose of the simple driveway swap.

BTW I found mine by using car-part.com
quick search in New England found wayyy more than comes up close to me !

pick your area + postal code

then search

window will pop up and you choose the 4x2 right or left

look in the description field and call to confirm pricing, availablitly, possible CASH discount for pickup or if they offer free delivery, and that they are indeed from a 2wd truck and not a 4wd

You say the banjo bolts are the same size. Any idea what year the change was? I have a 1980. I thought I read a different swap thread that said there was an adapter needed? Can't remember where I saw that

I think the adapter is needed if you use the s10 rubber line, but i am not positive. I went to rockauto.com and it tells you the banjo bolt size for whatever car you are searching for.

An adapter is needed if you use the S-10 rubber hose to the Malibu steel hose

Fantastic write-up... I am always amazed at the amount of cross-over there is with this car and the S-10/Sonoma chassis...

What was the total investment on the brake upgrade??

mine was a little expensive. I had one noisy bearing but decided to replace both for peace of mind. Upper ball joints and springs were replaced the summer previous.

$ 150.00 spindles used
$ 600.00 for 2 GM bearings
$ 120.00 for GM rotors and pads
$ 20.00 for 2 new flex lines
$ 20.00 paint and brake fluid
$ 120.00 2 new MOOG lower ball joints ( again for peace of mind )

Are you using the stock master cylinder?
