My GSX1400 Restoration

You can do it yourself Baz, there's nowt much to a caliper, but if you're really not confident, best to get someone else to do it or maybe another member down that way could give you a hand?

Mate, pull them apart, check pistons. Order what needed, not as difficult as some stuff youve done. Jaw up Buddy, youre an Aussie, not a Queenslander but still Aussie.

Haha, thanks. Pure Aussie here. I don't mind pulling stuff apart and bolting it back up and having a good old go but in cases like this I was looking at the pistons and I had no clue if they were supposed to be sticking out more or if there was some way to see if they were in good condition or if they were stuck. It seemed odd that they were all the way in. I had to push really hard to get them to go on a bit more and I wasn't sure if that was normal or not. This is where experience in something like this is essential. You have to know what you're looking for - especially with brakes. The shuddering on heavy braking was a bit disappointing and I flicked a switch that said "nope - time for a pro. Put it away." I just hope Suzuki doesn't disappoint me as well. I don't fancy throwing away $600 and still not having perfect brakes. If that happens you may see me on the news.

Mate,PM Del. $600 a lot, he might have something. His product looks flaweless.

Also check Masterbates. He had monoblocks, adapter plates and master cylinder for $450.

I had same problem, dragging brakes after cleaning.

Thanks, I read your thread a few days ago and yours cleared up after a  100km ride. My brakes do seem to work fine and have a much improved feel and I'd love to just go out and ride but the shuddering on very hard braking is a new phenomenon which concerns me.

Might try removing one caliper then the other to see if there's a clue there too.

go for a decent ride and re bed the pads in by gradually increasing braking pressure, try some hard braking in a  place that you can let the brakes cool down without having to come to a stop, do that a few time and reassess

Give them some time and let the pads to wear little more to adapt to brake discs again

[SA14]

I put the pads in back in the same calipers and side so they'll still need bedding again? If a bike shop had been asked to clean the calipers woukd they let it out the door like this?

Forgot to mention that the wheel spins fine without the calioers fitted.

Does the shudder/growning at the end of a heavy emergency brake concern anyone? It's new. Never heard it before and I test heavy breaking before I go very far on every ride. I only took it for a blip in first gear. Probably 30km/h max and it groans only at the very end right before total stop. And I can hear the brakes dragging when coasting with the clutch in. It's not horrifically loud or anything but it's there and new.

[steve porter]

bed them in again, as one pad wasn`t fitted properly it can`t possibly be perfectly matching the disc yet

[mlivkovich]

I really think it needs a good ride with at least 10 harder stops. Burn a full tank of gas riding it and brakes will be fine

[steve porter]

also, after bedding in ride along  for a bit and stop with the rear brake only and feel the front callipers, if cold , nothing is dragging

[GSXKING]

Time is of the essence. However if you wish to hasten that. Get it up to 200kmh and just hold the brakes steady as you slow down slowly. The discs will slowly face the pads for you.  ending with a much smoother stop afterwards.

I was contacted by an Adelaide member of this forum who assures me it's no big deal and if I screw up or get stuck he's got my back (thanks Josh!) so today this happened...(see pic). Plus all of you saying "pffft, you can do this Baz!" I'll give it a red hot Aussie go.

Next steps...

1) Pull it all apart and have a look inside.
2) If it looks like the pistons will come up ok and the o-rings and seals look re-useable try to put it all back together
3) If not, buy the Suzuki kit and try to put it all back together
4) If I screw that up take it into Suzuki in a Woolies bag and say "here - call me when they're ready to pick up"

He also mentioned that our type of brakes and discs aren't supposed to be bolted up using the "hold the brakes on and torque the mounting bolts" method. That may be causing the bind. In any case, the shudder on hard braking isn't confidence inspiring so apart they will come.
