Just finished installing speed bleeders in the Z (already installed them in the '94 when I first bought it). Absolutely one of the best things you can do for your car for only $20.00. :thumbs:
Honestly, I think it took me longer to take the wheels off and put them back on than it did for a complete brake fluid flush. And I don't have to recruit any "helpers" for this job.
If you haven't already installed speed bleeders you really ought to take a close look. Makes a huge difference.
I ordered both sets from Summit Racing .... they come in pairs .... I think I paid around $7.00 3 years ago and paid $10.00 a pair about 2 weeks ago.
I think the Vette catalogs have them listed but at a slightly higher price. You might find them referred to as Russell Speed Bleeders but I heard that Edelbrock or someone has bought the company. You might try AutoZone ... I think they carry them also.
So how do these work??? Do you pump the brakes and push the old fluid out and the speed bleeders keep the air from coming in like a check ball? I always wondered if they really worked. Sounds like a better and cheaper idea than getting a pressurized bleeder.
Just as you said. You open the valve just as you normally would but you leave it open and pump th brake pedal to bleed the fluid without having to close and open the valve as the check ball does that for you. Close the valve by tightening the unit down and it is all nice and tidy.
I think that the size for most C4s is 10mm x 1.0mm (front & back). When I called Summit I told them the year of the Vette and they knew exactly what I needed.
On my '90 the factory manual gives the order of RF, RR, LR, LF .... can't remember the sequence on the '94 but would imagine it to be the same.
I also used clear plastic tubing that fits snugly onto the bleeder nipple and allowed the fluid to drain into a clear jar ... makes inspecting the discarded fluid much easier, watching for debris, etc. Also, prevents any mess.
One thing to remember .... do not let your fluid level get too low or you'll be sucking air into the system. Just keep adding fluid as you work on each wheel. I usually do a complete rotation two times when I'm purging old fluid out and it usually takes about 3 cans (factory manual says 1 quart).
On my '90 the factory manual gives the order of RF, RR, LR, LF .... can't remember the sequence on the '94 but would imagine it to be the same.
Actually they are different. I am pretty sure my service manual list the '92-96 as RR, LR, RF, LF. It may be a difference in the ABS that causes the furthest wheel to be different.
What about working with the ABS system? When the vette comes back out of the shop, I DEFINATELY need to change/upgrade my brakes, and Speed Bleeders seem very promising. I've never done a brake fluid flush/change before, so is it going to make it easy with the speed bleeders? Do I need any sort of vacuum pump? Or do I just unscrew the factory bleeder and screw in the Speed Bleeder and then put a bucket under it to catch the brake fluid?

Re: Speed Bleeders Rock
Good to hear.
I have a set from Summit, but haven't gotten around to installing them yet. I should have ordered one for my clutch slave too. Has anyone done this? or know if they're available?
$10.00 for a pair at Autozone.
Toughest part for me was getting the old ones to budge! Propane torch and PB blaster applied a week before doing the job helped.
Rock on.
so is it going to make it easy with the speed bleeders? Do I need any sort of vacuum pump? Or do I just unscrew the factory bleeder and screw in the Speed Bleeder and then put a bucket under it to catch the brake fluid?
Yes .... many times easier w/speed bleeders .... one person job. No, you don't need a vacuum pump for normal bleeding/changing fluid. Yes, unscrew factory & replace with Speed Bleeder. When you're ready to do a wheel, unscrew the Speed Bleeder 1/4 to 1/5 turn, pump the brake pedal, keep the brake fluid reservoir full. That's it. Yes, you will need some kind of container to catch the old fluid .... you will find that using clear plastic tubing pressed onto the bleeder nipple will make the job easier/cleaner. Good luck.
You all are getting me motivated to install the speed bleeders I have on the shelf. Here is how I think the bleeding procedure would go, *please* correct me if a step is not right:
1. loosen speed beeder
2. remove brake fluid reservior lid
3. put a clear plastic tube onto speed bleeder and run to a bucket or jar
4. pump brake until reservior level drops
5. pour new fluid into reservior, keep adding it while pumping brake until the new fluid begins to come out the end of the clear tubing into the bucket.
6. tighten speed bleeder, remove plastic tubing
repeat for each wheel, in proper sequence. Top off reservior after last wheel is bled/flushed and secure the lid back onto reservior. Done.
