Weak front brake 04 ec300
 

Hey guys have a front brake question, ive put new pads on bled them every way possible but the feel at the lever is weak they work about 75% better once warm but i like my front brake super strong do i need to rebuild the master cyl or the caliper? Pretty sure my last gasser had a honda crf front brakr setup thanks in advance

Sounds like you have air in the system. Did you try to bleed the brakes? One quick method is to push the caliper pistons back in the caliper and it will force some (maybe all) air back through the master cylinder and into the fluid reservoir. Sometimes it works sometimes it does not.

Yes like i said i tried everything would like to save some money if i dont have to buy both kits

Get a zip tie and pull the lever as far back as possible. put the zip tie on around the bar and lever let sit over night.

With bleeder cracked? Also what other bikes have same master and caliper? I know japs are the same but need a year or years lol

The zip tie trick works, but the trapped air rises to the highest point of the brake system. ie usually the loop in the hose. raise the resevoir or lower the caliper.

No do not crack open the system. You mite do like hamilton said or just undo the line so you can pull the line to the side so the master is the highest point but I have never had to do this but it could not hurt.


Any year XR400 front and back

How is the air released? If theres no escape for it

It just goes into the master cylinder try it it mite help mite not but it is free:D

I got it zip tied right now thanks for the tip!
