T-BRAKE fixed Rear Brake Disc for KTM SX 85, SX 105, XC 85, XC 105 2003-2010

The T-BRAKE AX36-257 brake disc is designed for KTM SX 85, SX 105, XC 85, XC 105 from 2003 to 2010. The disc, bolted to the hub, is the surface the pads clamp onto. It has to stay flat and thick enough to get rid of the heat: a tired disc lengthens stopping distances and wears the pads.

Specifications

• Brand: T-BRAKE
• Manufacturer part number: AX36-257
• EAN code: 8050040141302
• Engine: 2-stroke

When to replace it?

• Thickness below the minimum stamped on the disc or given in the manual.
• Warped disc: vibration through the lever or pedal, brake that “pulses”.
• Deep scoring, cracks or blueing after overheating.

Measure the thickness with a micrometer every time you change the pads, and replace the disc as soon as it reaches the minimum thickness, or if it's warped or cracked.

Fitting tips

1. Clean the hub mounting face: a single grain of sand under the disc is enough to throw it out of true.
2. Fit the disc the right way round (markings facing out, direction of rotation if indicated).
3. Tighten the bolts in a criss-cross pattern to the manufacturer's torque, with medium-strength threadlocker.
4. Degrease the disc and ideally fit new pads.
5. Bed in with a dozen progressive stops.

Frequently asked questions

Should the pads be changed along with the disc?
It's strongly recommended: worn pads have taken on the shape of the old disc and won't brake well on a new one.
