ok, ive had the prob over a week now, first caliper had well and truly seized, had to order second one of ebay which came yesterday.
bolted everything on, put everything back together, start pouring in brake fluid and it starts gushing down side of bike- i didnt open bleed valves cause i havent done this before!
luckily i dont think it got on the paintwork, just the exhaust and swingarm.
then spent the next hour trying to pump through the fluid, press the lever, open valve, close valve, release lever
although the fluid has gone down a bit in reservoir, it aint coming out bleed nipples yet
I also got that proper red grease for the pistons to stop them seizing up, but im too scared to let them come out when i get pressure incase they dont go back in (like the old one)
I also need the bike mot’d by friday…
so is there anyone that can give me a hand? plssssssssssss
ive already spent a hundred quid and cant afford the garage to do it!
If you don’t have anyone closer to you, I’ll give you a hand - recently had someone help me change my hoses, so feel pretty comfortable doing this now. I’m in Woking.
No guarantee the second hand one is going to be any good either. When I had trouble with mine last year they needed new seals all round. It is fiddly and messy and when I gave up and took the bike to the dealer because it failed the first MOT then was not fixed by the time I went back for the second MOT a week later it was not cheap either
You need bleed tubes to bleed the brakes properly unless you have a cunning helper who knows what they are doing. Brakes are one thing on the bike that should not be messed about with unless you know what you are doing.
Well i was able to push in the piston before i put the caliper on, thought the idea was you fill up the brake fluid, pump them till the pistons slide out partly, lube them, push them back in…
I was using a bleed tube, like i said, pressing the lever to squeeze through the fluid, and closing the nipple before releasing the lever so that it didnt suck in any air
Its a two man job really though, hence why i thought someone might be able to give me a hand
Sounds like you know what you are doing. I can’t get over there to help unfortunately, stuck at work. Not sure if you have braided hoses or not, if you do, and the caliper bleeds are only producing fluid bleed from the Banjo bolt next to the master cyclinder on the handlebar. If you have a clear plastic tube going to the reservoir you can usually see small bubbles coming up the tube. Keep tapping the brake lever and you will witness them rise into the reservoir.
Its a new braided line ive put on, had thought about bleeding from the banjo bolt itself, but theres no fluid coming from the nipple itself yet
unfortunately the tube from the master cylinder up to the reservoir is rubber, so i cant see how far down the fluid is going, i only know by the fact the level in the reservior has gone down a bit.
maybe it just takes patience, but i spent about an hour last night, and this morning feel like ive wrenched my arms from their sockets!
I had a mate help me when i changed the front lines, and after about 2 hrs pumping etc, we had to go to someone else who had a compressor
Thought the back wouldnt be so bad as ther wasnt too far it had to travel
