Brake fluid.

[_Iain_]

Tiny leak on the bottom piston of the caliper on my GS500, brakes still work, happy days.

How does one go about rebuilding the caliper? Take it off, squeeze lever pop pistons out, scredriver old seals out, bosh new ones in, copper slip round the pistons, back in add fluid, bleed, happy days?

Next question, how do i get brake fluid off the tyre? Had the front slip in a right hand corner which was pretty scary tbh. Closest i've been to decking a bike yet.

Ta much!

Coppaslip ONLY on the FACES of the pistons, or the back of the pads, NOT on or near the piston seals or caliper bores. IF you must grease the seals, use rubber grease only. Or leave them dry.

Pump the pistons out nice and far, use a block of wood /something not metal to block the freer moving pistons if you need to get more than one piston out. Use only brake fluid, or red rubber grease on the pistons and seals themselves.

The important thing is to check the condition of the seals and clean the crap that has inevitably built up in the seal groove out with something soft (wood/plastic, no metal). You can wash the caliper in soapy water, rinse it thoroughly and dry it in the oven on low heat if you need to get a particularly stubborn bit out.


Copper grease on backs of pads (thin smear) and a bit on pad pins if you like. It's a suzuki so copper grease pad retaining pins to stop them seizing. Loctite threadlock the caliper holding bolts.

Soap and water will get the brake fluid off your tyre. If you get any on paint, wipe it off quickly with a wet rag.

Next question,

Have replaced the seals, all the fluid, pads (ebc HH sintered) and still spongy as. The line looks a bit iffy, very old a little perished. It bulges slightly when i apply the brakes. Brakes are 100% bled, no leaks, good pads, good fluid and still feel a little unresponsive and spongy...

I'm assuming new line required, if so braided or standard? Pros/cons.


Oh and the fairy liquid/scrubbing brush combo worked beautifully!
