Brake fade?

WINNER WINNER you get the award because you figured it out (IMG:style_emoticons/default/smilie_pokal.gif) great minds think alike....once again guys....... thanks for the input

Heat buildup can cause alot of problems.

* Do you still have the big metal splash guards on? They get hot and hold the heat in your rotors & calipers. like little brake ovens (IMG:style_emoticons/default/devil.gif)
Take them off if you haven't already.

* Brake coolers? These kits to route air into the center of the vented rotor help alot.



* I use ATE Blue and have no problems but change out annually. I've heard MOTUL is good but have no experience with it.

Did you bleed the proportioning valve too? That little gem can give you all sorts of grief if it still has air in it.

Pads. with all of the above, I still had fade with 'good pads' until I switched to Pagid Orange....


Let us know what you find and what fixes your problems...

I had some brake issues recently and it ended up being a frozen piston in one of the front calipers. Was real exciting first high speed lap on practice day!!

It stops strait and true with one hand on the wheel...no pulling at all.I assume that means it OK ??

You probably don't have a sticking piston then... I had a pretty noticable steering change when the brakes were applied. Helped turn ins going left though!

And from above. The brake coolers do work with a stock valance and the Pagid Orange pads don't squeal in my experience anyway. Great pads, but with the devaluation of the $ they are around $200 an axle! (IMG:style_emoticons/default/shocked[1].gif)

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

"They dont (sic) flex like stocks (sic)". You've been reading too much hype on the 'net from people who don't know of what they speak. They probably don't speak/write English, either. The Cap'n

[ericread]

Pagid orange will be ordered tonite for sure.Do they squeel?

Yes. But they squeal a lot less than you will if the brakes fail... (IMG:style_emoticons/default/wacko.gif)

yes splash guards on but not for long good idea..I did use the blue but just changed to the MOTUL heard it was better?? 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.

Will do! cars on block now so i will be chase`n as soon as i get home.I have AX on Saterday....Thanks for all the input I will let you know what i get figured out

Just to throw this out there....but.... if you've got stock 5 lug Carrera brake rotors, and 16" wheels, you can upgrade your front calipers to REAR 993 set. It takes a very small amount of modification to the caliper holes, but that's it, and WOW is the braking great.

Many years ago, I upgraded from stock 4 lug to the 5 lug set up and brakes/rotors from an 84 911. Worked well for a long time but when i went to the bigger engine, it was crap during racing conditions.

One day, we looked at a set of 993 brakes I had and figured "heck, looks like the rear 993 calipers could fit the front of the 914". Viola, EXCELLENT brakes. No fade ever.

I use braided lines, MOTUL fluid (higher bp than blue), rear calipers didn't change from the old Carrera set up, and Hawk blue all the way around. I love them, very high level of confidence in braking. Wanna see? check out some of my in-car video's on www.naroescapemotorsports.com. The 2007 Road Atlanta race video shows me out braking a bunch of cars into 10a, and the Watkins Glen into turn 1.

[sww914]

FYI, I've had the same braided flex lines in my system for 10 years. One of them failed when my frigging car caught on fire! It got melted so I replaced it.
They did help the pedal feel, they did not improve overall braking performance except that they made pedal modulation at limit braking easier.

Factory -6 with 5 lug as you know! but 15 inch fuchs .Pads are good so i think im just gonna try the bleed thing again and find that(per Porsche ning valve) (IMG:style_emoticons/default/av-943.gif) and try that first.I just bought a motor and i dont have tons of $ to spend on stop`n.I know i know its fun too go like hell but man you gotta stop too .I only do about one or two track days a year mostly AXand they work alrite for that.Thanks for your input GOOD LUCK IN CAROLINA...cool video

Holy smokes batman I watch that blue and yellow 6 go in the ditch in Newfoundland(on TV).Lots of damage but the car finished the race.I would give my left U no what to do that race

well didnt alot of stuff fail when it was on fire ..or it failed and then the car cought fire because of the failure?? (IMG:style_emoticons/default/confused24.gif)

[DanT]

Your problem is not in your braking system. It is in the "braker" (IMG:style_emoticons/default/biggrin.gif)
one or two track events per year. Over braking would be my diagnosis, not a problem with the brakes themselves.
Nothing unusual with someone that does not do very many track events.

just my 2 cents. (IMG:style_emoticons/default/confused24.gif)

[So.Cal.914]

Heat buildup can cause alot of problems.

Thats a good kit, Or you can get the Home Depot version. (IMG:style_emoticons/default/biggrin.gif)

[jhadler]

Ducting, ducting, ducting...

Fresh good fluid, and REAL track pads, will make a big difference. But the 914's have notoriously poor airflow to the brakes, so get some kind of ducting in there to the front brakes, and you're likely to see your brake fade problems go away for the most part.

Other issues... Pads. "Performance" street pads will NOT survive at the track. If you're going to track the car, get real race pads. Keep in mind that real race pads are not going to be nice and quiet, clean and friendly like street pads. They eat rotors like a kid at a ball park eats dippin' dots, they can squeal like a banshee, and make an awful mess with dust (both from the pads and the rotors). But, they will still be there to save your arse the next weekend while "performance" pads can likely be nothing but a set of backing plates at the end of the first day.

And yes, the stock proportioning valve is a PITA to bleed if it gets air in it.

-Josh2

edit - Oh yeah, and experience... A newer driver to the track will tend to overbrake more often, and that puts a hefty burden on the binders...

[Crazyhippy]

Dont use the brakes so much...

People used to race these cars w/ smaller brakes than you have, and survived.

[PeeGreen 914]

Just get them bled well and we can talk about it on Saturday. I can help you in getting the parts you need. Remember that Tim and I get things at cost. Call me if you have problems bleeding them.

[Eric_Shea]

Race914, Josh and Dan have nailed it.

If you simply did a DE event and your brakes are fading (especially M-Calipers with vented rotors) you have some issues. Hate to say it but the issues are probably with that large nut behind the steering wheel! (IMG:style_emoticons/default/biggrin.gif)

If you're planning on doing more DE events (and why wouldn't you... it's the most fun you can have with your clothes on) read up on braking techniques and/or ride with a hot 914 driver. You'd be suprised at how little the brakes are used. The other thing mentioned is the AJ cool rotor kits. Those things work wonders. Get some air to them and use the ATE Blue.

You "really" shoudn't have seen brake fade as described at a DE event. Make sure your fluid is brand spanking new and the good stuff and please keep an open mind to braking technique. Maybe Brant can jump in here as he is out racing lap after lap with similar calipers etc. and he should have some "seat time" answers for you.

Hope that helps.

[DanT]

M calipers and vented SC rotors on the front with 914-4 fronts on the rear, T in the rear line (no prop valve). Fresh Pentosin fluid...
3 continual hours of lapping (cherries jubilee charity event) giving rides to hot rodders. This was at Laguna Seca, which is notoriously hard on brakes.

no fade, no need to bleed....

it is not your brakes. (IMG:style_emoticons/default/biggrin.gif)

QUE??? QUE???? (IMG:style_emoticons/default/biggrin.gif)

maybe the Rx doctor could prescribe something for it (IMG:style_emoticons/default/blink.gif)

oh, you say it's brakes!... my wife seems to think if she flails around enough and hits the "pretend pedal" the car will come to an abrupt emergency stop, from the passenger side no less

who needs to stop 2 p anyway? (IMG:style_emoticons/default/stirthepot.gif)

seriously, hope you get the info you need

Yep, that was us. Up until that point the car was running perfect..... but....it was the perfect culmination to a lousy week.
