- Do not spill brake fluid on the vehicle, it may damage the paint; if brake fluid does contact the paint, wash it off immediately with water.

4. Remove the brake tubes (A).

Tightening torque:
18.6 - 22.6 N.m (1.9 - 2.3 kgf.m, 13.7 - 16.6 lb-ft)




5. Disconnect the brake tubes (B) from the HECU by unlocking the nuts counterclockwise with a spanner.

Tightening torque:
13.7 - 16.7 N.m (1.4 - 1.7 kgf.m, 10.1 - 12.3 lb-ft)




6. Pull up the lock of the HECU connector (C), and then disconnect the connector.
7. Loosen the HECU bracket bolts (A) and nut (B), then remove HECU and bracket.

Tightening torque:
Bolts (A) :
19.6 - 29.4 N.m (2.0 - 3.0 kgf.m, 14.5 - 21.7 lb-ft)
Nuts (B) :
8.8 - 13.7 N.m (0.9 - 1.4 kgf.m, 6.5 - 10.1 lb-ft)





CAUTION:
- Never attempt to disassemble the HECU.
- Never shock the HECU.

8. Remove the bolts, and then remove the bracket from HECU.

Tightening torque:
10.8 - 13.7 N.m (1.1 - 1.4 kgf.m, 8.0 - 10.1 lb-ft)
