Finding the Motorcraft BRSD1069 Front Severe Duty Pad, which was superseded by BRSD1333, which was superseded by BRSD1631. All are available with the BRSD1069 being the more expensive. Can someone tell me the differences in the pads? Thanks.

 

I can't anymore. They are flipping new formulations since my time.

 

I went with Wagner pads

 

Both Motorcraft and Wagner come from the same plant, Motorcraft has a tighter spec on fit and finish. The formulations are often different.

OE pads from Federal-Mogul come from a different plant, and different spec's then Motorcraft.

 

As another gentleman posted, I went with Wagner Thermo Quiet pads and at 26K they are holding up well. I have been using Wagner products for over 30 years and I usually get a rebate back. They have intelligent customer service where you can actually talk to a human being. I pull a 10K+ fifth wheel. Save yourself some money - go Wagner.

 

Good info.
Has anyone thought of having John adding this to the Tech Folder?
That or adding it to a parts list that may be floating around.

 

According to my Motorcraft distributor, the BRSD1631 is the current "superduty" blue brake pad. This part number does supersede from the older BRSD1333, which in turn is superseded from the oldest BSRD1069 "Severe Duty" blue brake pad. My guess is the oldest is likely the best. Good luck, Russ

 

My 6.0 F350 Camper is 6.5 metric tons heavy. Are there any brake pads that "bite" better? To brake hard I have to press the brake pedal pretty hard.

 

Better than the severe duty pads? You’d have to go aftermarket to a more aggressive compound. I really like the severe duty pads, more “bite” than other pads I’ve tried, including Performance Friction Z Rated. And Performance Friction only makes top quality stuff.

 

I wouldn't say they only make top quality stuff.

And Motorcraft is "aftermarket". It's OEM, not OE, as in assembly line installed.

The older Z formulation from the '90s was pretty good, it was OE on the front of the OBS. But not having good compliance would crack the rotors with hot spotting when the brakes were pushed hard. Put them with a drilled rotor and your asking for it.




You can't say the oldest is the best. It may have been, or newer formulations address complaints from customers. Or newer formulations met a better price point so the Ford dealer could be more competitive against the retail parts stores. Outside of being in the Ford upper management or supplier loop, no one can know. not even the distributor.

Most of the world in the aftermarket tries to sell in the friction range of 10% of the OE assembly line parts. In fact, in Europe, it mandated while we have no rules. Some specialty aftermarket manufacturers do up their friction, it gives them the "better stopping" rep. You can up the friction, but you will always sacrifice something for that. It usually is rotor wear, but can be noise or pad life. It's going to be something.

Powerstop is an easy example of this, as they note by number in their Evolution series. Often these companies package with a specialized rotor and people are very enthusiastic about the rotors. Doesn't have a damn thing to do with the rotors, they are just spending more money for a specialized rotor that doesn't actually do anything for them. At the OE assembly line level the target for friction in either E or F by edge code. For 6.0s, '99-04 were FE, '05-'80 were FF. But they both hovered around a 0.35 coefficient of friction. Hawk LTS comes in at FF, but the hot F is higher, around 0.40

You can get Power Stop way higher, in an area that many OEM would not go, an HG friction code. While some think it's great, at that high a friction it becomes harder to pedal modulate at low road friction surfaces. Yeah, that's a Superduty pad.

I would recommend Hawk pads. They brake a LOT better, with less effort, then OEM with very little dust. They are pricy, the fit is excellent and they are available in many flavors for trucks.

They actually stop in the same distance as OE, but the pedal effort is lower and because they are a high metallic with a higher friction level. They have a higher thermal threshold if your 15k trailer's brakes fail. They "come in" during the stop as they need heat to obtain the best friction level. They are currently on my truck.

One thing that is extremely important. A disc/disc brake system on our trucks does not follow the old school drum brake situation of front brakes do 70 to 80 percent of the work. The '99-04 brakes were about 55/45 and the '05+ around 60/40. So if you put higher friction pads on only one axle you will shift the braking balance. That changes the heat energy, for wear and thermal degradation.

In the early '90s, FedEx contracted with PF for the service replacement brake material, taking it away from Ford over the counter. They developed situations where the driver would make a delivery and have no brakes when they got back into the Ford vans. Both PF and FedEx head service honcho gave a presentation at an SAE brake conference I attended where the presentation was about the need to check brake fluid for its boiling point. From that, we got the electronic testers and television ads by people like Midas about checking your brake fluid. It also got us phenolic pistons.

The damn thing was, the FedEx mechanics were bleeding brakes. The change in friction brought the heat dissipation of deceleration to the front brakes. The classic Townes Pass brake fluid boil test done by OE is to run the route, park the test vehicle, then check for the fluid boil after sitting. And that's what FedEx drivers were doing, heating up the brake assembly, hand-delivering while the thermal transfer was occurring into the calipers, then experiencing pedal to the floor.

I went up to the FedEx director after the presentation and explained what was happening. They changed to a higher friction product and the formulation had a higher thermal transfer rate. It took about a week before my company president and I got a letter from SAE with a reprimand since at those meetings your not supposed to do things like that. Sometimes you can't fix stupid.

Hawk pads are high metallic, with a high thermal transfer rate. You need to do routine brake fluid servicing.

 

I ordered BRSD 1069 from Amazon for $74 and received BRSD 1631 which I could have bought for under $50 from other reputable sellers. They will either credit me the difference or they can take these back. Box states "FABRIQUE AU MEXICO".

 

The Federal-Mogul aftermarket plant that manufactures Wagner and Motorcraft is in Mexico. There's a second plant that makes shoes for drum brakes. The OE assembly line brake pads for the US are made in Smithville, TN.

Other plants across the world make other applications, often under the Ferodo label.

 

Jack, any thoughts on "performance" rotors i.e. dimpled, slotted, cross-drilled, fancy coatings, OE on the Batmobile etc.? Are there practical benefits or just marketing? Russ
