Posted: 09:15 - 25 Apr 2017 Post subject: Binding front brake |
|
|
Story time...
The front wheel on my GS500 has been getting squeaky for a while, last week I replaced the front disc and pads since the disc was well past its service limit. Squeak still there.
Last night I stripped the caliper down, cleaned and greased the slide pins, cleaned out the hydraulic side and assembled with new seals, now I think its binding worse than before. Also fitted a new (HEL) hose, because no idea how old the previous one was.
If I apply the front brake and then let it off, the pads remain stuck against the disc hard enough that it turns for about 3/4 of a revolution before stopping. I'm pretty sure this isn't a (just) fault on the hydraulic side as when I ran it up and down the road with the pistons pushed fully in I'm sure I still heard a slight squeak.
The GS500 caliper has one slide pin in a blind bore in the body, the other in a through hole with a rubber boot wrapped all the way around it, the latter on mine isn't central and I have no idea if thats normal.
How freely should the caliper slide? Mine offers some resistance when inserted properly, no resistance if only the blind-hole pin is inserted, with the bracket clocked around 180° or so.
I'm not sure if the seals may be incorrect or badly made - I had to resort to a G clamp to get the pistons through them, don't think I've ever had to do that before.
Any suggestions what I should look at next?
Thanks |

The caliper is manufactured by AJP, looks identical to the other ones for sale like this one.
EDIT: Fowlers are in on the "Suzuki didn't make any GS500s after 2002" conspiracy it seems |

Looks like I won't be able to get the seals for this: linky.
Gonna try a few hydraulics suppliers after the bank holiday, failing that, get a different caliper I suppose...
Is this sort of shit normal for Suzuki? Never had this much trouble getting service items for /any other bike/. Not even ones from the 70s/80s that barely exist any more. |

Right, SV650* caliper rebuilt using the "GS500" seals (perfect match) and its still binding a little bit
Not as bad as before (wheel will do a couple of revolutions when span), but still enough for an annoying squeaking when moving.
auuuugh.
* purchased from a breakers since the seals/etc are still available |
