Overview
The Baer Brakes 99205-020 is a rear Claw performance rotor set for the 2015–2017 Ford F-150 in 2WD and 4WD with an electric parking brake. It is a direct replacement, so it installs in place of the factory rear rotors on those trucks.
Both rotors are cross-drilled and slotted, which lets gases and dust escape from between the pad and rotor during braking. The cast iron rotors are one piece, and the zinc-plated finish suits open-center wheels. The design is premium and mill balanced.
Key features
- Cross-drilled and slotted friction face that routes gases and dust away from the pad
- Chamfered cross-drilled holes that Baer says reduce stress cracking
- Enhanced vane structure that Baer credits with cooling and durability
- Zinc-plated finish for an appearance behind open-center wheels
- Premium, mill balanced direct replacement rotor
- Vented, conventional rotor with a directional brake surface
Wear limits and reuse
Rear rotors wear gradually, and the thickness at the friction face decides when they should come off. A rotor worn toward its minimum thickness will heat up faster and may flex under clamping force, which shows up as pedal pulsation. Measure at several points around the braking surface, not only at one spot, because uneven wear is common on the rear axle.
On electric parking brake trucks, the rear caliper also carries the park function. After rotors are replaced, confirm that the parking brake applies and releases normally, and check for dragging once the wheels turn. If the hub face was previously fitted with another rotor design, clean it thoroughly so the new set seats flat.
- Measure thickness at several points around the rotor
- Look for scoring deeper than a fingernail catch
- Replace pads when the lining nears the wear limit
- Clean rust from the hub face before fitting
- Check for blue or discolored spots that signal overheating

Vehicle fitment
Baer lists these rotors for the 2015–2017 Ford F-150 only, for the rear position in 2WD and 4WD trucks. Baer ties the fit to trucks equipped with an electric parking brake.
The list does not include 2018–2020 F-150 models, and it does not cover any F-150 with a manual parking brake. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The rotors have six lug holes on a 135 (5.315) bolt circle, so check that the rear hub matches this pattern before fitting. The center hole is 3.54 (89.9), and the discard thickness is 20 (.787), so measure worn rotors against that figure when servicing the axle.
What’s included
A matched set of two rear Claw rotors with no other parts listed.
Not included: brake pads and other friction parts.
