ABS Pump Assembly

The brake fluid pump servicing process starts with air cleaner case and air cleaner hose removal before removing the master cylinder. The precharge pump connector must be disconnected before uninstalling the precharge pump assembly by loosening its 3 bolts at a torque of 19 Nm (195 kgf-cm, 14 ft. lbs.). The precharge pump brake line connection requires Special Service Tool: 09751-36011 to separate them from the precharge pump while applying 15 Nm (155 kgf-cm, 11 ft. lbs.) to the 10 mm nut and 20 Nm (200 kgf-cm, 15 ft. lbs.) to the 12 mm nut. The precharge pump removal process includes disconnection of its 2 nuts and 2 bolts while tightening them with 13 Nm (130 kgf-cm, 9 ft. lbs.) and 8.0 Nm (82 kgf-cm, 71 inch lbs.) torque respectively. Later remove the 2 holders, 2 collars, 2 washers, and 4 cushions. Apply the socket wrench to remove the master cylinder pressure sensor by securing the precharge pump with a cotton-wrapped vise. Use a 30mm deep socket for the operation under 81Nm torque (830 kgf-cm, 60 ft. lbs.). Installments are executed by reversing dismantling steps then fluid must be added to the brake reservoir before performing a brake system bleed and carefully inspecting all fluid-deducting points.

Start the brake fluid pump service and repair procedure by removing the air cleaner case followed by the air cleaner hose and then uninstalling the master cylinder. Disconnect the precharge pump connector before taking out the precharge pump assembly by loosening the 3 bolts to 19 Nm (195 kgf-cm, 14 ft. lbs.). Special Service Tool: 09751-36011 should be used to disconnect the 2 brake lines from the precharge pump by tightening the 10 mm nut to 15 Nm (155 kgf-cm, 11 ft. lbs.) and the 12 mm nut to 20 Nm (200 kgf-cm, 15 ft. lbs.). Eliminate the precharge pump by first unscrewing and unbolting the 2 nuts and 2 bolts at 13 Nm (130 kgf-cm, 9 ft. lbs.), then disassemble the 2 holders, 2 collars, 2 washers, and 4 cushions. A 30 mm deeper socket wrench should be used for master cylinder pressure sensor and O-ring removal while applying 81 Nm of torque (830 kgf-cm or 60 ft. lbs.) after securely placing the precharge pump in a vise with cloth. After completion follow the opposite sequence of removal while performing fluid filling of the brake reservoir followed by brake system bleeding and checking for fluid leaks.

Detach the 2 holders, 2 collars, 2 washers, and 4 cushions.
