I am going to do a brake job on the front and rear of this IS F Sport. The owner says it's an IS 250 F Sport manufactured in September of 2014. I need the steps, procedures, diagrams, exploded views, and torque specs to properly do the job. Most specifically besides the information on the front brakes, I need the rear information especially concerning the parking brake shoes that are in the rotor hat. I did this job a few years back and now that I am doing the front and rear brake job again with all new parts, I want to do the rears more properly because I know it was harder with the rear parking brake set up. Also, a detailed procedure for how to bed in the brakes would help as well. Cheers

Hello, the parking brake shoes do not affect the ability or difficulty of a rear brake job on this vehicle, unless they are rusted to the drum, or unless you are planning on replacing them. Make sure the parking brake is off before beginning this work. I will attach the exploded diagrams and the procedure below. There is a type A and B for this vehicle, however the instructions are the same for both, be sure of what shape brake pad you have to compare with the new one.

Upon installation for both sides, the caliper piston must be pressed in, which is easily done with a large C-clamp and the old brake pad. If you are planning on bleeding the brakes anyway, I would crack the bleeder on the caliper and press the fluid out of the caliper this way.

After making sure the brake fluid is at an adequate level, you will need to step on the brake a few times to seat the pads, and to begin bleeding you will need a helper or tool of some sort to keep the brake pedal down. Starting from the furthest side (passenger rear), you should pump the brakes 3 times, hold, crack the bleeder and wait for the fluid to stop, close the bleeder, and pump the brakes again. Keep a check on the brake fluid level during this time. You should be able to do 3 rounds per wheel, and as long as you don't hear or see any air / bubbles in the fluid you should be fine. I like to connect a small hose leading to a bottle for easy cleanup.

Please let us know if you have any other questions.

Thanks William. In the parentheses when I look at the torque values, is the one on the right foot pounds and the one on the left inch pounds? Also, what is an A or B type? Can you explain? Thank you

Hello, the number on the right in parentheses is ft/lbs. Type A and B are simply two different brake pad shapes, and does not affect the procedure in any way. Just make sure the pads you are using match what is on the car.
