Alright, gearheads, let’s dive into the nitty-gritty of the SS4+ brake system. This setup is built for those of you rocking 15-inch wheels on your classic rides, specifically the 1971-1973 Ford Mustang and Mercury Cougar. It’s not just about looks; this system packs a punch with a 4-piston caliper paired with an 11-inch, 2-piece slotted and drilled rotor that’s zinc plated for that extra durability.

One of the standout features here is the stainless steel brake hoses, which are a must-have for reliability. Plus, the calipers come with D.O.T. compliant dust and weather seals, so you know they’ll hold up against the elements. And let’s talk about the hardware—Baer uses NAS high-grade stainless for the pre-assembled rotor, meaning you won’t be worrying about rust or wear anytime soon.

Now, if you’re thinking about fitment, you’re in luck. This system is designed to work seamlessly with the disc brake spindles of the 71-73 Mustang and Cougar. So whether you're keeping those classic 15s or planning to upgrade to something bigger, you’ve got options without losing that stock vibe.

Why go with the SS4+?

• It gives you all the performance benefits of Baer’s larger systems but in a compact form that fits your 15-inch wheels.
• Everything you need is included, from hoses to fittings—just grab it and bolt it on (General fit applications aside).
• The hat is made from 6061 T-6 billet aluminum, anodized black, and securely bolted to the rotor.
• High-grade U281 fine thread stainless hardware with captured nuts means you won’t be hunting for parts mid-install.
• And those hubs? They’re 6061-T6 billet machined with Timken or SKF bearings already installed, packed with Redline synthetic grease, so you can hit the road without a hitch.
• This setup can even work with your existing rear drum brakes if you’re not ready to switch everything over just yet.

Let’s break down the caliper features:

• Four 10mm cross bolts for maximum stiffness—no flex here.
• Stainless steel abutments and noise suppression springs keep things quiet and smooth.
• Hard anodized aluminum pistons for durability.
• Internal crossover design that simplifies maintenance.
• Dual seals—dust/weather and pressure—to meet D.O.T. specs.
• Each caliper has a machined logo that’s hand-painted, adding a personal touch.
• Uses a common 4-piston pad for easy replacements when the time comes.
• Comes in a sleek silver powder coat finish, but if you’re feeling adventurous, custom colors are available.
• Available for both front and rear, so you can keep that matched look all around.
• And yes, Baer sticks to the correct banjo style fittings, avoiding any pipe thread nonsense.
