Hi,
I've been fighting a front brake problem. The front tire only spins about 2 times with the tire on and the rotor only spins about 3/4 to once without the tire on. I just wanted to know what everyone elses did.
Thanks,

Are you saying that your brakes are dragging a little?
Scott

That's what he is saying.
He is having trouble with one brake dragging. I referred him to the threads on brakes dragging. Exchanged PMs with him about the problem.
I am thinking that the sliders are worn or caliper may be sticking a bit. The front wheels will never spin like they did on his go karts.

I've greased and cleaned the sliders. I am going to put new calipers on, but just wanted to know how much others spin. I also bled the breaks

I have had the same problem before. I have one that free spins and the other doesn’t no matter how much I clean. I know that you want it to spin and go eat dinner and come back it is still spinning but the reality is that is not going to happen on these cars. I did have a friend that used springs to help pull the pads back. He drilled a little counter sunk hole and attached a spring. Problem was that the tech guy didn’t think it resembled anything that was delivered stock but it did work……LOL.

I know that these are not going to spin for a long time, i however would think that the rotor should at least spin around one complete time.

I pm'ed as well on the other thread and gave direction on exactly what to do, but you told me you were told to do someting different...

I've been told to do many different things and am just trying to get ideas. I tried the sliders and that didn't seem to work, I am going to replace the calipers because i believe that is my problem. I just wanted to know how many times everyones tire normally spins to get an idea what to look for as a fix

It can only be a couple things:
-caliper piston sticking
-master cylinder rod not adjusted properly
-slides
-
One wheel spins 3 or four the other only once. I guess I could work on them myself now you got me thinking about it.

Hmm does the left side spin more then the right?
Thanks,

Dan as matter of fact it does. It would be great if it was the other way around if it has to do it at all. I'm going to pull and repack the wheel bearings also. I'm building a new car so I will take a closer look in a few days.

...or wheel bearings, warped brake rotor, bent steering arm off the spindle causing contact with the wheel (pesonal experience).

It seems that most cars are like that. I however think that my calipers are bad since i did a test and they don't seem to open back up.

What calipers are you using and what are you planning on buying? I would have the rotors turned. Also make sure the rotor is in the center of the brake shoe bracket, I have seen tweeked brackets be the cause many times, either of the brackets being off will cause excessive pad drag. i suggest 2" calipers as a replacement, replace both. The master usually causes both to drag not just one. Hope this helps.

I'm using brembo front brakes, I was told not to get the brembo rotors turned because they don't like to be turned.
Thanks,

Sorry, but BS... Unless you change brake pads on a VERY regular basis... Rotors should be turned enough to clean them up. Brembo's are no different than any other.
Turning the rotors should just take the grooves out of the rotor. More than that, then yes, the rotor may need to be replaced.
MHO,
Steve

No rotor "likes" to be cut. The thinner it is, the faster it will warp.
-
I have raced and built winning Legend Cars for 12 years. If you spin the rotor and it is warped, have it turned. These rotors need to spin true, end of story. i have raced rotors cut to the min. for weight and I have raced brand new rotors thick as can be. It made no difference in the braking, guarantee it. I have races every caliper you can buy, brake man is the best, BUT THEY ARE VERY EXPENSIVE! i now rebuild calipers using my own rebuild kit that i have put together, they are half the price and just as good as brakeman calipers. I do not suggest the 21/4 caliper sold by US Legends, sorry i am a dealer, its not a good product! Run good fluid, good bearings, good calipers, and MAKE sure NONE of the brackets are tweaked. These master cylinders are notorious for hanging up, make sure your is not. i promise you I have spent thousands on brake pads, calipers, lightening, honing and on and on, its not necessary! e-mail me and I will be happy to share my experience with anyone FREE of charge!

Sorry for all the questions i am brand new to legend racing, how do you check to see if the brackets are tweaked? also how do you check to see if the master cylinder is hanging up?
Thanks,
Dan

I won't argue that any time you turn a rotor that it makes it thinner and perhaps more prone to warpage. True enough. I was just saying to "true it up". If the rotor is that far gone that you would need to cut it paper thin; Then it needs replaced.
Calipers, like brake cylinders, need to be rebuilt every so often. They sometimes stick, or the pistons get worn. Nothing a rebuild kit and a light cylinder honing shouldn't fix. I've never had a master cylinder hang up. It could happen. They are not dis-similar to the calipers or wheel cylinders.
Dan, Your questions are just fine. Not only the newbies are looking for answers to the questions you are asking. As Dennis alludes to; light weight, most expensive, the latest trend, etc...does not necessarily make it better.
To check that the caliper is square to the rotor is a simple matter of using a square, laser, or tape measure. I don't think that your problem is as big as you think it is. Granted, I think the wheel should spin more than 3/4 of a turn. While it is off season, it is a good time to rebuild your brake calipers and brake cylinders. Especially if it is an older car, or hasn't been done for awhile. Clean and repack the bearings; Or replace. Balance the wheels and tires. Regardless, the front wheels are not going to spin anything like your kart wheels did. Just the drag from the front brakes will cause the wheel to spin less. I do think that there is a problem somewhere though if both front wheels are not spinning a similar amount.

Thank you for everyones help. I have been working on the brakes and am putting new calipers on and also will consider getting the rotors turned. If that doesn't fix the problem i will probably work on the brake lines and change them out..
Thanks,
Dan

Don't think the brake lines are going to be your problem unless they are too small. ???

Dan,
I recommend re-reading my PM to you in direction on how to resolve your concern. I covered all of the elements given by others in one reply. If you follow those recommendations you issue(s) will be resolved.

I have been using your email as a guide. I have already cleaned and greased the slides and that didn't do anything. I figured i sound do the calipers next. I did a test and they don't seem to be opening up like they should be so i figured i should start fresh and put new ones on.
Thanks,
Dan

well i am pretty sure that I have solved the problem. I had a bad master cylinder. When i pulled the caliper off I was getting a flow of brake fluid out of the lines. In addition i am switching brake fluids to the wilwood stuff so i am in the process of totally cleaning out the system

Vern said that Jim doesn't use brakes........................Sorry but it had to be said................. ;D
Scott

LMAO!!!! Jim had brakes? ???
Of course Vern should likely have picked a better place to work on his finger nails. ;D
Dan,
Of course you will get some fluid coming out of the caliper when the master cylinder is disconnected... It's down hill.

Right, i know i'll get a little, but when having the line off for an hour completely drains the resivour i figured i had a problem, in addition i had the line up so none should have come out

Actually, the master cylinder will drain to the level of the leak if the hose is up until the reservoir seek the same level. This is the way the master cylinder was designed which also allow you to gravity bleed the brakes.
If you new one doesn't drain like your old one, something is wrong.

Right, But when the master completely drains from the right caliper, and when i pulled the left caliper off no brake fluid came out until i let the line down. And my problem is on the right side

Dont think I had a chance to hit the brakes...just driving around, minding my own business and POOF, theres Vern giving himself a french manicure while parked sideways.

This long lasting battle seems to be over, both sides seem to be about the same now, i put new calipers on, and a new master cylinder. I'm going to be ordering new rotors since now that there free i am able to feel that there warped.
Thanks for all the help
