Front Brake replacement problem

[Canuck]

Hey guys,

Ran into a problem after i installed the front brake pads.

They are in contact with the disc without having pressure on the handle.

do i need to air bleed the brakeline now?
or.. use a "C" Clamp to push the pressure back on the master cylinder(if that is the correct term)?

or... is there always supposed to be a hair of contact between the pads and the disc...??

CORRECTION...
Brake Piston**

Either way... i have begun to bleed the brake system and... of course somehow screwed up..


now i have constant "sponginess" and my brakes have no power.

Great.

So... umm I dont know where i went wrong here but i guess ill read the manual on bleeding the system OVER ..and OVER in hopes of getting it right.

(I really need to just leave things alone.. ) *sigh*

Brother;

Disc brake pads are always in contact with the rotor and the caliper piston. That's the way they are supposed to be.

To address the sponginess, re-bleed the brakes using someone else to pump the lever for you.

The procedure is, pump the lever 5 times and hold. Open the bleeder on the caliper, releasing fluid and air. Close the bleeder and release the lever.

Repeat until the lever feels firm again. (4 or 5 times is usually sufficient) Be sure you keep the fluid reservoir full.

Good luck.

Sarris its working now... i had to be more patient with letting the airbubbles come out fully.

then i could feel the tension..

As long as you say so Sarris.. I just thought that there would be a hair between the pad and the disc but its not enough to really feel any resistance so I'll let it slide..

Thanks for the input


by the way .. i dont think i kept the reservoir full 100 percent of the time..

Just remember to wash off any brake fluid that gets on paint or chrome, it will eat it away in no time.

Funny you said that bonehead...


Put the master cylinder cap on my seat... left marks...

I guess fate is directing me towards a custom seat :lol:

Ya, sorry I did,nt read the post sooner. Brake fluid will really screw paint and such up.

If you don't have a second person handy to hold the brake lever while you bleed the line, try using an elastic band or zip tie to hold the lever in.
