Customer Question

I have a 2007 Harley1200 Sportster , I changed both front and rear pads. I wanted to replace the brake fluid in both the master cylinders . The front worked before but the rear never did work .Now Neither one will draw a pressure. I bled both several times . I've done cars for years as a Tech ,never seen anything like this before ??

it can be frustrating.

the best way I have found is to use a syringe type bleeder and force fluid into the caliper to collect in the master cylinder reservoir.

let me know if you need more help.

I tried that and it didn't work either .
Expert:  Steve replied 1 year ago.

you need to continue trying until you get all the air out of the lines.

there is not trick to it......it's just air and you need to get it all out before your brakes will function correctly.

you need to be patient and persistent.

I tried several times to get back to you. Nothing you've suggested has worked ! I've bled it numerous times when you watch the master cylinder ,front and rear, both just show the fluid
Circulating NO air Bubbles , I've pumped over a 12 oz. through the front alone !

motorcycle brake line can be frustrating.

your options are to remove the air from the brake lines OR take your bike to someone who can.

there is no trick to it.

it's not magic.

the choice is yours.

in either case, I have answered your question.
