Im gonna treat my bike to some new pads now ive had the calipers cleaned out.
not a clue how to do this? do i need to bleed the brakes? need to replace any seals? is it just a case of unscrewing the bolts an taking the caliper off the disk? |

if u are just changing your pads it is best to do it with the calipers in situ(easier to undo bolts and stuff that way)... although u may need to take one off temporarily to remove the front wheel......once u have done this and the caliper is back on, wrap a rag around the base of the reservoir on the handlebars(to save your paintwork) and take the top off.......then using 2 screwdrivers apply even pressure to both sides of the old pads inside the calliper to ease the pistons back squarley( try to get them right back or u may not get the disk in between the new ones )......once this is done on both sides, remove the lugs covering the retaining pins with a flat head screwdriver then loosen the pins with a hex/alan key....
now would be a good time to open your new pads and give the backs of them a coating of copper grease(this stops em squeeling and prevents corrosion)
as u take the pin out use 2 fingers to hold the pads in place(this will stop the anti rattle clips flying out)...... then u remove the pads ;).... if u take care when doing this the little clips should stay in place... again use the copper grease on the thread of the retaining pin, insert the new pads, push the pin back in and hand screw to hold them in place( at this point do not tighten the pin as if u have a prob gettin the wheel on u may need to backtrack )....
repeat the procedure for the other side then put the wheel back on(remember to remove a caliper or your tyre will get in the way and also coppergrease the thread of the bolts u take out).....
once the wheel and callipers are back on, tighten the now greased retaining pins and replace the lugs covering them, also having put a bit of the copper grease on the thread.
next stand by the bike and operate the front brake lever, it will feel squidgy to start but will stiffen up quickly....once this is done, swiftly pull the lever in and let it flick back quickly, repeat for about 5/10 mins and watch inside the reservoir you should see any air that is trapped in the top of the system bubble back up into the reservoir.....
once this is complete.... u need to bleed the system from the callipers.....
to do this, use a bit of clear plastic tubing( i got some from halfords, it was to replace screenwash tubing on a car ) and a suitable container to catch the fluid.
put one end of the tube in the container and push the other end over the bleed nipple, operate the brake a couple of times then hold the lever in, open and close the bleed nipple on the calliper watching out for air bubbles trapped in the tube and repeat as neccessary......once u are convinced there is no air coming through, top up the reservior and repeat the bleeding proccess on the other side.....
now both sides are complete top up the rerservoir for a final time..... put the top back on and tighten the screws( copper grease on these is a good idea too as they easily corrode ).... and wipe up any excess fluid.
Now all you gotta do is go for a ride mista, taking it easy on the front brakes for a bit until the pads "bed in"
Enjoy ;)
P.S : once u put the wheel back on just check at intervals that it is spinning freely ;).
if there is anythng peeps wanna add or have spotted that i have missed out, please do mention it as brakes are quite important lol .... thx Seeb's |

How clean are they is the question?
Nice guide, although I would suggest before pushing the pistons back, that they are sprayed with brake cleaner. Get this from car accessory shop, use an old toothbrush and spray & brush. This stuff shouldn't be breathed in!
Also clean any shims/spacers the same way. Don't know what your caliper is like as I have a CB-1, but as it's apart, you should (if it is this type?) pull it apart. May have to remove a bolt to do this.There are probably piston / pistons on one side only, the other side is floating on sliding pins, these can seize.
Once apart, clean all the inside with toothbrush & cleaner.
Push the rubber bellows GENTLY from the bore it sits in. Clean this metal bush inside and out as directed above. This should when cleaned be a free moving fit over the sliding pins.
This is the hard bit, as it is hard to get hold of... "red ruber grease" put some of this on the outside of the rubber bellows and slide them /it back into the bores. put some more inside the bellows, and refit the bush. Ensure that the bellows "lip" is engaged in the groove in this bush, grease the inside of this bush. Then reassemble.
Red rubber grease does not attack rubber, whereas most other greases do. Although I've read that silicone grease is ok to use. Also put a smear of this around the diameter of the pistons, this will lessen the chance of them corroding & seizing your brakes.
I've recently done this on the CB-1, my BMW 1150 GS, & my partners Yamaha XS650, point being that it is easy, and gives a sense of satisfaction, as all of them had a minor gunged up / corossion problem ongoing. |
Alcohol is the answer, if only I remembered the question |

Hi Guys,
I'm planning on painting my calipers and replacing the pads either this week or next week so i'd like to strip them right down (remove the brake line). Can someone tell me the exact steps for stripping them right down, including removing the brake line (do i just unscrew it) and what i should watch out for? Also can you tell me how i should go about replacing everything?
Regards,
Chris |

bleeding from empty is a PITA and best avoided if you are inexperienced. Can you not do this with the line still on?
Brake fluid is massively corrosive to paint and it is very very easy to spill a little bit on a freshly painted caliper while bleeding it back up. |
