Overview
Part number 05575-020 is a pair of vented, cross-drilled and slotted front brake rotors from Baer Brakes, made for the front axle of two-wheel-drive Chevrolet, GMC and Isuzu trucks and SUVs from 1991 to 2003, including the S10, Blazer, Sonoma, Jimmy and Hombre.
The Claw design lets gas and dust escape from between the pad and the rotor, which supports a more consistent pedal and reduced brake fade. Each rotor has a zinc-plated finish and a one-piece full cast body in cast iron. The ABS tone ring is included with the set, which matters on vehicles that use a tone ring for ABS. The outside diameter is 266.7, the overall height is 51 and the discard thickness is 24.5.
Key features
- Vented rotor design rather than solid.
- Slotted and drilled friction surface with chamfered cross-drilled holes.
- ABS tone ring included with the set.
- One-piece full cast construction in cast iron.
- Zinc-plated disc finish with a directional brake surface.
- Premium grade type and emission code 6.
Trucks, tone rings and daily use
Front brakes do most of the stopping on these two-wheel-drive trucks and SUVs, since weight shifts forward under braking. Vented rotors move air between their two faces, which helps them shed heat during repeated stops, such as stop-and-go driving or towing, though they still need good pads and clean hub faces to run true.
Because the ABS tone ring is part of this set, check that the ring sits flat and that the sensor gap is correct before reassembly. A bent or damaged ring can cause ABS warning lights or erratic wheel speed readings. Front wheel bearings and steering components should be inspected at the same time, since looseness there shows up as runout and vibration.
- Torque lug nuts in a star pattern
- Re-check lug torque after a short drive
- Inspect front brake hoses for wear
