Brake Issues

Looking for opinions on a brake upgrade.

I currently have Purple Hayes F&R with 8" rotors and I just can't seem to achieve strong braking power. The brake lines have been replaced, genuine Hayes pads are new(ish), and I'm using DOT4 fluid ... but nothing helps. Everytime I bleed the system with my little leach kit, some air pockets exit at the top (lever end). Even after a fresh bleed, the brakes are still mushy, to the point that sometimes the lever comes all the way back to the bar. I have even had the LBS bleed the system with similar results.

I guess I have a few options.

#1 - try out the new Goodridge stainless lines (might be worth a shot)
#2 - full rebuild of current brakes (master cylinder and/or calipers)
#3 - install complete new brake system

What I want is a solid brake feel without too much play.

Cheers

Purple Hayes are very good, strong brakes.

Take it to a bike shop that can fix the problem as it could be a leak in any part of the system and a good mech should be able to figure out where it is.

Any suggestions for a good shop on the Shore, as the current shop I go to can't seem to fix it (going by past results).

Cheers

you could have a deteriorating piston seal, at either master cylinder or slave cylinder.

go to Steed, we deal with OGC ( the deals hayes brakes) on a weekly basis and the OGC head mechanic will even come in to take at look at serious problems. But if you hayes are falling short, i know a dude that got the goodridge lines for his hayes, and notices a great improvement in braking. Some other great brakes for the Buck are the 4 piston XT or new saint brakes!

i get all my work done at BSP NV. it sounds like your bladder in the lever is split or it can also be the plastic were the bleed screw tightens into being cracked. this happens if ham fisted mechs over tighten the screw

Weird that you are having problems. I'm still on stock hardwear (hoses and everything) after more than 2 years on my Hayes Purples, and have no problems. I would have dropped Hayes a long time ago if I was having problems.

There is either something currently wrong with one of the parts of the brake, or it isn't properly bled.

If your current shop hasn't been able to fix the problem, go to a different shop.

If the system is bled fully, and then cleaned well, you should be able to tell if you've got a leak somewhere.

Goodridge lines will improve that system, but there is something else wrong that you need to take of first.

Thanks for all the input folks.

I'm gonna try once more with the current Purples and see if I can't get them fixed properly. The possible bladder leakage/crack sounds like my next area of attack.

Cheers.
