Spongy Brakes on my 1100

Postby moneypit » Fri Aug 29, 2014 7:34 am



I'm a firm believer in synthetic brake fluid. I also believe in swapping out the old for new. My 83 needed rear pads I installed them but my brake pedal was still quite low and spongy, I bought syn. brake fluid used my old battery tester to suck out all the old fluid then filled with new fluid and started the Bleeding process until new clean fluid came out of the caliper . I did front rear and the front brake WOW what a difference Now I have a solid brake pedal and awesome brakes. So if you haven't changed your brake fluid lately or ever try it you be amazed at the results.

I replace the brake and clutch fluid annually regardless of mileage. It's just a good idea.

I was never happy with the brakes on my 1100 either - they always felt a bit spongy and weak to me. With 30+ year old rubber brake lines, it was no wonder!

I replaced my brake lines with a set of HEL braided stainless steel brake lines, and it transformed my brakes. They went from weak and spongy to strong and razor-sharp. It was the single best upgrade I did to my GL1100, and I would highly recommend it.

Have you done that to your GL1500 yet?
I have the replacement lines and will most likely tackle it this winter.

I've put them on the front wheel on my GL1500. I have not yet put them on the rear (although I have them waiting to be installed), as it requires significant disassembly to get to the brake lines. So I'm waiting until the next time I have the bike torn apart, then I'll do the rear as well.

Did you change the reservoir? Mine is looking like it is seen much better days and I don't want to put new lines with old parts that will fail. I've seen some cast ones on eBay. Any recommendations?

Just to add my nickels worth; I replaced the brake lines with the HEL braided ones on my "83 A, and it made all the difference in the world.

No, I did not. I did rebuild it, which replaces all the innards (piston, seals, etc.) but the reservoir typically does not wear out, so unless it is damaged, it doesn't normally need replacement.
