Oh yeah, now that you say.....
stock brakes rebuilt by Eric shea. Haven't braked with them yet as I'm still putting them on. sounds to me like you need a good bleeding if your pedal is mushy or maybe your pads are dragging and wearing unevenly. I seem to recall a thread about this written by someone totally awesome.... http://www.914world.com/bbs2/index.php?sho...acing+my+brakes There we go (IMG:style_emoticons/default/idea.gif) |

Are you already 5-lug? Some vented rotors, Porterfield pads, and fresh fluid ought to fit the bill (if the lines are good).

Add air ducts to calipers (See Trekkor). Also, ya get 'rm hot enough the rubber seals will go away and you won't have any brakes (and the fluid coming out catches on fire real nice). Parking lot .... no answer. |

I'd check your brake system for leaks, cracked hose, etc. I'd do this before you drove the car again. Zach |

Parking lot .... no answer. sorry guys I should have been more specific.But yes track session at Portland.brand new Motul fluid all the way through the system and a good bleed ,good pads,good slotted rotors up front, good calipers braided lines I guess i just didn`t expect them to go away so fast ,I didnt think the fluid would boil that easy.it was hot outside about 80+ and i thought once they cooled i would get some back ,but they just keep get`n worse.I agree a bleed is in order.And again sorry for the confusion |

Nice pic....
ARent braided lines unsafe for not being able to check your actual line condition? I read somewhere, i think from sir andy or lapuwali that the braiding can abrade the hose on the inside and you'll never see a failure coming... how about venting clearance? How about braking less?

(IMG:style_emoticons/default/poke.gif) good point on the braids! but they dont flex like the stocks so you get better feel in the pedal and they dont bulge under hard brake`n.Well the stop`n things kinda tuff ,go`n 115+ and try`n to stop or at least get down to 30 in 400 feet is tuff with out break`n very hard and do`n that twice a lap at Portland..venting system is stock so i would say not much if any .I will be bleed`n` em tonite...thanks for the input |

Pagid orange will be ordered tonite for sure.Do they squeel? , .how can i tell the proportion valve thing if its not bled proper..will the vent kit work with a stock front valance?..Thanks I'd probably start chasing the problem in this order. 1. Take off the splash guards. 2. Bleed brakes again. I agree with the post above, you may need to bleed several times if there is any residual moisture, etc. 3. Bleed the proportioning valve. Search here for threads. I use a Motive brake bleeder and tap the proportioning valve lightly to dislodge any bubbles while bleeding the back calipers. Do a search though, I'm sure there are better methods : ) Then try the brakes again. I wouldn't change out the pads or add the coolers right away. See if the above makes an improvement first. Also, if the brakes work if you keep pumping them. And if the pedal slowly goes down if you apply constant pressure while sitting still, you may have a master cylinder going bad. If you change that out, upgrade to the 19mm unit. |
