Title: Brake Master Cylinder Post by: The_Matrix_Master on February 21, 2011, 01:25:41 PM The brakes on my Spyder have gone a bit "Spongy" ! 1st press of the brake pedal and there is a fair amount of travel 2nd imeadiate press of the brake pedal and the brakes are back at their best. Since there is no discernable drop in the brake fluid and I cannot find any leaks at the pipes or nipples I an assuming the master cylinder is on its way out ? As a new cylinder is about £85 and repair kit is about £15. I thought I would go down the repair kit route. Does anyone know if the Beta Spyder repair kit is comparable with a later day car ? The fiat X19 cylinder and repair kit is compatable with the Montecarlo but not the Beta Spyder. Can I buy this kit over the counter at a local motor factor as I can see the kits on the web for around £15 in the UK for the Beta Spyder but they want £5 P&P for what is basically rubbers that you could send in an envelope at the cost of a 1st class stamp. I have found a kit in the States for $12 but they wanted an unbelievalble $35 to ship it LOL Cheers :-\ Title: Re: Brake Master Cylinder Post by: rossocorsa on February 21, 2011, 09:12:35 PM original part number was 82293524 or 82369266 it is common to Gamma and possibly (not 100% sure) to Fiat ritmo/strada 130tc
have you tried a really thorough bleed using an easibleed or similar device and renewed your fluid? Title: Re: Brake Master Cylinder Post by: JoeBeta on February 21, 2011, 10:23:13 PM Would agree, sounds like you just have some air in the system.
It can sometimes take several attempts at bleeding to get all the air out. I would have thought if it was the master cylinder, the peddle would continually drop with constant pressure??? Title: Re: Brake Master Cylinder Post by: The_Matrix_Master on February 21, 2011, 11:37:35 PM Thanks guys.I never really considered that the problem may be down to air in the system or fluid past its best (Doh!).
It seems a sensible place to start.I will renew the fluid and bleed as see where I get. Cheers :) Title: Re: Brake Master Cylinder Post by: MattNoVAT on February 22, 2011, 06:06:11 PM Over time the brake fluid absorbs water/moisture and becomes less effective.
Start with furthest caliper from master cylinder and flush through until new fluid comes through the bleed nipple. If it's still spongy then M/C might need to be replaced. But do the fluid first as people have suggested. Good luck! |
