Front Brake Still Spongy After Bleeding.

[Aleks]

I have a Honda Varadero XL 125 (53 plate).
The front brake seized so I rebuilt it.
I then had a spongy front brake so I bled it.
Still spongy so I tried every 'trick' in the book that Google gave me.
Got slightly better but still insufficient.
Bled the brakes again with expensive brake fluid, still crap.
Got braided brake lines, improved slightly but still crap.
Googled lots of methods to bleed brakes and tried them all, STILL CRAP

pls help

I can't even lock up the front wheel when the lever is touching the grip, what should I do now?

Thanks in advance!

Have you bled them thoroughly? Check out Jake TheGardenSnake's video:

.... have you also ensured you cleaned them fully?

The brakes have been bled properly as far as I'm aware, I have tried elevating the caliper and bleeding it, emptying and refilling with fresh fluid, cable tying the front lever shut overnight. Also, when the I squeeze the front brake bubbles do come out of the master cylinder very slowly, but I have probably bled it 4/5 times now and it doesn't make a difference. Cheers for the reply.

Have you checked that none of the threads are crossed? The system is airtight?

I haven't checked if the threads are crossed, but I will check that as soon as I get the chance. Unfortunately I am quite heavy handed so it might be a possibility, although there are no leaks anywhere.

What brake fluid did you use.

Don't say dot 5

Thats ok

Sounds like the problem is in the master cyl.

think there is air in the bajobolt. at the mastercyl
sometimes you need to losen up that one to get the air out there.
