Scion 90931-01137 Hose, Clutch

When removing the Clutch Hose, it is important to be prepared for the loss of brake fluid. To prevent air from entering the braking system, have a plug or tape ready to seal the reservoir once the hose is disconnected. The pressure pipes can be removed by unscrewing the union connections on the Clutch Master Cylinder and at the bulkhead, and then removing the pipe. Use penetrating fluid and a brake union spanner if needed. The second pressure pipe is similar, with the union nut being unscrewed at the top of the transmission and at the Clutch Slave Cylinder. The high-pressure flexible hose is fitted between the rigid pressure pipes at the bulkhead and the transmission. To remove the flexible hose, unscrew the union nuts at the hose-to-pipe connections. When refitting, ensure tight and clean connections, and bleed the clutch.

To examine it, raise the front and rear of the car off the ground on a level using an appropriate car jack. Inspection of unions to find out that they are not leaking and to check on the flexible hoses for cracking, or chafing and fraying especially at the front caliper. Check brake pipes for dent, corrosion and damage, remove corrosion and replace the pipes if it has severe pits mainly from direct exposure. Replacing any brake pipe or hose that may be damaged is another check up the should be conducted. To minimize brake fluid loss when unbolting a section of pipe or hose, either unscrew the filler cap and seal the reservoir's opening with cling film/ tape or drain it. To remove and disconnect the pipe one need to grasp the adjoining hose union nut with a spanner to secure from twisting and then turn the union nut of the pipe end till it is loose and then unscrew the union nut on the other end before finalizing the detachment of the pipe from its clips. If these nuts became tight expose to weather use split ring spanner to prevent damaging the flats while self-locking grips can be used as the last resort if the pipe is liable to renew. To reduce the chances of loss of brake fluid during the disconnecting of the flexible brake line, apply the clamp on the hose at the end of the rigid pipe. For the removal of flexible hoses, the ends should be cleaned with water and other suitable agents, the union nuts unscrewed and the spring clip removed in order to pull the hose from the support bracket and unscrewing from the caliper if any. Brake and fuel hose with flared ends and union nuts are available at the dealers or from accessory shops, to shape the new pipes they are bent with the aid of the old pipe but it is very important not to kink or crimp the hose. Refitting is basically conducted in an opposite pattern to removing and in the process all brake pipes should be supported and the hoses not kinked or be located near the suspension. Last of all, it is recommended to bleed the hydraulic system when done.
