It will become easily rounded out when attempting to perform the brake bleed. See attachment.īTW, the Bleeding Edge screw in the caliper is very soft aluminum.

I want to pass it on to save someone the aggravation I went through, a trip to the lbs, or unnecessarily tearing apart the system. I also found this Park Tool video for Sram brake bleeding which validates the above quote – minute 2:46 If it is all the way out, you will be unable to pass fluid from the rear caliper to the lever, regardless of anything else you might do.” “In addition to the other (more drastic) suggestions offered, I would check that the travel adjustment screw on your brake lever is not all the way out. But finally, I came across a key piece of advice which was applied to Sram mtb brake bleeds: My set up is less than a year old and I installed it myself the first time without issue. I couldn’t find anything about road bike AXS blockage. I even thought about just buying a new left lever and caliper, but there is nothing available for sale out there! Google searched and read stuff on forums by people who also experienced blockage, but on their mountain bikes. I was dreading the thought of disconnecting the line again, dismantling the caliper and the lever in search of the cause. The rear brake bleed went fine – no problems with the bleed procedure.
I followed the Sram video precisely, but still no success with the front. Upon doing a bleed the syringes would not budge on the front brake.
