I first want to apologize if this has already been asked/solved in other post. I tried to search and didn't find exactly what I was looking for.
I just installed Front/Back Toms steel brake lines and pads. When I press the brake it is soft and figure I have a lot of air in the lines.
Can someone explain how to bleed the brakes on the RCF? or if you have any other ideas.
Thank you for all the help as my car will sit until I figure out the soft pedal.
I would presume you just bleed the F out of it. 3 or 4 cycles. Until no bubbles and new fluid comes out. Usually farthest is rear passenger, rear driver, passenger then driver.
Glad you’re not driving it. If you’re unsure of how to bleed properly, find someone to help you. Sounds like you’re a bit vague on this topic..
I assume you drained the whole or most of the reservoir installing the lines so it will take a lot of fluid to get all the air out.
Use clear hose to bleed so you can see the bubbles. Check valve helps or get a second person.
Keep bleeding until no bubbles are seen in the line.
Do not over torque the bleeder screws. It takes very low pressure.
If you use a clean container, you can recycle the bled out fluid and put back in reservoir.
Bleed in the order from farthest to closest.
Do it again to double check for air once you completed all 4. This time just bleed very little.
Good luck. Be safe.
Most of the time manual bleeding is sufficient, but if your pedal still feels mushy or not as solid as before, you'll need to activate ABS to get all the air out. I haven't had to do much work on my RC F, but I assume you would need to use Tech Stream to activate the ABS pump/system.
Thank you guys for the responses. I should have been more specific on my question. I am having issues locating the Bleeder screws on the RCF. The RCF setup is different from other cars that I have changed brakes on.
Where specifically is the Bleeder screw on the caliper? I know this is simple for some but this is my first time bleeding brakes on the RCF so all help is appreciated.
It was hidden by the brake sensor. I haven't had to deal with a brake sensor before and didn't realize that it capped the bleeder screw.
Thank you guys again! It also helps to work on the brakes in the day time versus 10pm at night.
Before doing this, I would do this: https://www.clublexus.com/forums/rc-...-and-gs-f.html. The bleeder is at the top of the caliper on the inside with a rubber cap on it. Brake bleeders are always at the top of the caliper so any air inside rises to the top to be purged. The cap is attached to the pad wear wiring harness. See pic:
