Upon bleeding my brakes, I get no fluid flow to the LR caliper. Any ideas on how to proceed to troubleshoot? Thanks in advance. 2008 RX400h

Want to add, that I removed the caliper to see if the piston was sticking. Piston is fine - was able to compress it. Also lubed the caliper pins. Verified that no flow getting to the caliper by cracking open the line - there's fluid there, but no flow upon depressing brake pedal.

Separately, I posted that after the bleeding (3 of 4 brakes) the ABS & VSC lights are on. Brakes are still spongy. No air was observed during the bleeding process.

kpiemeir, fyi, you can edit your post (to add to your original post) so you do not need to create another.

Sorry to tell you but you cannot bleed rears on a 400h( i know from experience) like the 'normal way' . You will need techstream or will need to get someone with techstream to do it. The program pushes the fluid through electronically from the OBD. The nipple is cracked and closed in the usual manner.REMEMBER: keep the fluid high!!

I already told him this in his other post. L line is likely simply electronically locked. He needs to pray he didn't bust brake actuator, it's very costly error to do.

Took to Toyota dealer. $111. All is well. Thanks for your help!!!

the owner manual should state that brakes cannot be bled manually.

With a 3rd generation RX, so not 100% sure if it's applicable to a 2nd gen, to bleed the rear brakes, the ignition needs to be in the ON position (engine doesn't need to be started), otherwise brake fluid will not flow.
