Big Brembos, Tiny Budget.

A pair of black cobalt SS brembos turned up at one of my regular yards, M & M auto Salvage in Stafford VA the other week. The hardware and pads were almost new, so I kept them and didn't spend the extra dough on new ones.



I have been wanting to get these since they are a 90% direct fit on the later build 9-5s. But couldn't justify the retail price on Genuine.

I needed to get some other parts, Including the 214mm 9-3SS Aero rotors, so I had the auto parts store next door order me up some Centrics.

These will fit under the dust shield on the 06-09 cars with the 308mm fronts.

I also got the Cobalt SS caliper retainer bolts. GM # 11570091

And these Roller bearings. The fit inside the hub bracket on the saab since the Cobalt SS bolts are a little smaller.
McMaster-Carr


There was arguments back and forth on SC about custom lines, but it was said that the stock line with the smaller Brembo banjo bolt. I was going to go this route but couldn't get this far.

I have to order up some 5mm spacers and lug bolts, since these wheels need to be moved out further.


So for now, they are on my floor.


For a 06-09 9-5, you will need an E20 torx. Order one ahead of time, nobody carries them.


These are the brakes bolted on, but not plumbed. Need the spacers.

I have installed these, and one major thing that needed to be done was removing some material from the calipers to get them just right.


These are the 314mm rotors from the 9-3Aero I am using.


These are the rotors the caliper is used to using. If I read this correct, the Saab rotors are 2.3mm thicker than the cobalt ones. I believe this gave me the major clearence issue on the Pass side. Seems also if I used the Chevy rotors, I would need to use more than a 5mm spacer.

Next week, I plan on removing my drivers and pass side rotor, and having the machine shop remove some material from the inside of the rotors. This is probably something I would recomend for folks to do ahead of the install.

Also check the room for the pad as it wears down. Mine looked to be catching in the slide area and I filed a small bit of material out of the area the pad frame would slide against as it wears. I also gave the 2 edges of each pad frame a quick zip with a roto grinder and a schmear of copper grease.



This thread was a big help on SC.

Wow, pretty cool!

This is for 06-09 only or could it work on the older (mine is an 03) Aero's with the 308mm brakes?

Curious about wheel clearance too, assuming only 17"+ would fit and you wouldn't be able to run 16's in the winter.

So wait, the 9-3SS uses larger rotors then the 9-5?

Still though. I wonder if the clamping force is higher in the 9-5 calipers.

This would be a great upgrade but I really like running my 16's in the winter up here in NH. 17's would just be too harsh and I'd probably chew up too many rims on the way to and from the slopes.

I think that is a very cool modification. You stated the only issue with the front is the dust shield correct ? That means you could use a later model dust shield on the older 9-5's ? The rotor offset should be the same ? I'm also wondering how economical the calipers would be once a recycle yard identifies them as Brembo calipers ? What calipers are on the back of the SS Colbalt ?

Not as important as larger Diameter Rotors...

the RPO code for the TC Cobalts is actually LN4. the brake system that uses these caliper is the JL9 call out.

the RPO codes for the brembo rotors are as follows.....

JL9 = BRAKE SYSTEM,POWER,FRONT AND REAR DISC,ANTILOCK FRT & RR DISC ANTILOCK BRK(JL9)

JL4 = CONTROL ACTIVE BRAKE ACTIVE BRAKE CONTROL(JL4)

LNF = ENGINE GAS, 4 CYL, 2.0L, DI, ALUM, DOHC, TURBO, GM 2.0(LNF)

perks of working for a GM dealer!

I know that the front end of a 9-5 is way different than that of a og9-3 but would these be able to be fitted to say a viggen?

the viggen rotors/calipers are the same as the 9-5 aero.... so to answer your question... yes!

4. 2 on each side as the caliper is of the fixed design.

That's actually a pretty good deal for brand new calipers, especially 4 pot brembos. $250 a piece. And if they are new there is no core charge.

Let's not forget they come powder coated black.
