GSXR 750 Problems - Forks and Rear Brake.

[Mej]

Well where to start.

Basically rear brake stopped working the other day on the way to the quay, pushed down and there was nothing there and the foot peddle has a lot of travel in it. Replaced the pads as they where old and it still doesnt work, its got fluid, so im not to sure now? I think it may need bleeding but i aint really sure how to do it.

Had new rubber put on today and the guy and tyre centre noticed that my right fork leg is cracked at the bottom and coming apart, apperantly someone put the fork bolts in the brake calipers and the brake bolts in the fork and they were too short so it has cracked at some point. Now i got a quote for a new lower leg and it was £230 without fitting!! The guy reckoned i would be better off buying a whole new set of forks and just replacing the whole leg rather than just the bottom part. I have seen a set on ebay for 233.50 and the guy said he would fit for £30 so before i buy them i wondered if anyone else knows of where i could get some on the cheap as last time i fcked up not asking here first.

51110-35F00 Part Number it is the RH Inner tube.

Also does anyone know where the list of fork travel distances is for the gixxers?

Cheers

The cracked side compared to the good side.


good side

What are the chances of it actually snapping as it is now held innplace by the right sized bolt.

You really wanna find out!?

If i was in your position, I'd probably buy the forks from ebay, have them serviced and refreshed while they are off the bike and then have them fitted. Then I'd chuck the old set back on ebay, pointing out the cracked bottom and just recoup as much as possible selling them for spares/parts.

Rear brakes - Try giving them a bleed. If you don't know how, then take it to someone who does to either learn or just to get it done! It's a handy skill to have and really not that tricky once you know how. If that doesn't work then you'll know further diagnosing is required.

Bleeding brakes - Not very difficult. Get a bleeding kit that has a one-way valve in (Halfrauds do one) unless you want to be constantly tightening and opening the bleed nipple (you dont!); a pot for the waste fluid to go in; brake fluid (preferably new, if brake fluid gets wet the water vapourises and causes brake fade as the fluid heats up).

Maybe change the fluid completely (definitely a new container!) If doing this pump fluid out and replace.

Cover all the bits of your shiny new bike the brake fluid could get on with rags, wrap a cloth around the master cylinder reservoir (pot for fluid by lever) to catch the inevitable spillage.

Remove reservoir cap, plate and diaphragm, set aside in a clean place. Remove the bleed nipple cover (bleed nipple is a thingamy with a hex-head, a hole and a plastic cover at the top of the caliper), put the ring end of a spanner over the nipple. Attach bleeder kit (or clear tubing if you're a stingy get). Loosen bleed nipple, pump brake lever. Brake fluid will go down your pipe. If you aren't using a valved bleeder kit you need to tighten the nut before releasing the brake lever, and loosen again to pump. Do this until no air comes out, KEEP ONE EYE ON THE RESERVOIR. If the holes at the bottom are exposed you are introducing air into the system and you will be there an age until it's gone. If you are being good and changing the fluid at the same time NEARLY empty and refill reservoir a few times to drive old fluid out of the caliper. Close bleed nipple, replace cover, top reservoir up to fill mark, check diaphragm, plate etc are clean and but back. CHECK BRAKE WORKS. Before riding CHECK AGAIN!. For front calipers clamp one line off at a time, and bleed/ change one at a time (since you're doing it...)

Just make sure the BRAKES WORK before riding. BTW, get shot of that fork. Some things, like fairings and speedo's aren't vital. Bits that could dump you on the deck if they break are, don't chance your arm!

I have been looking at these do you reckon they are worth it??

Do not risk it in my opinion, 230 quid could potentially save your life its a no brainer. then as said before sell your old one and recoup as much you can. i would pay tht money for them, you may find cheaper but tht doesnt sound like silly money to me depends on how much you want to ride it compared to finding a cheap pair of forks. good luck!!

well i have found a guy stripping down his old 750 track bike, with forks that have done 15000 miles and have just been serviced with new seals for 120 so that looks promising.

Exact same thing has happened to 3 or 4 chaps on the SV1000 Forum.. and guess what.. they all but one had been bolted up with non standard (Suzuki) bolts in fact the same allen bolts you have on you fork legs...

[Mej]

what the leg snapped?

They bolts are the original ones now but im not risking it so i havent ridden it since (weather has been corking as well) and have no way of getting about at the minute!!!

I think it was pretty bad that i had it serviced recently and they didnt notice but the tyre place did.
