i have a 2001 300ex which i just got and dont know much about but i just replaced the rear brake pads with some ebc pads and now the brakes wont work i heard form some one that if you dont push the piston in right you mess up the the brake system and need to get a new one is this true? or can i just get a brake rebuild or something

 

Did you bleed your brake lines?If you didnt you probablly have air in your brake lines.Or if you didnt use the right kind of brake fluid it wont have enough pressure to work the piston. Also check all of the seals for leaks.

 

yes i did bleed the brakes but i didnt put any brake fluid in it should i change it? and i think the seals are fine i dont see any leaks

 

I would go check to see if you have any fluid. If you dont, bleed the lines again and fill it up. If you do have some in it just fill it up and try bleeding them untill you get good pressure.

 

thanx 89exrider ill try that today and see if that works but do you know any good pipes that arnt that loud and still add alot of performance

 

My friend has a White Brothers pipe on his, its not extremely loud but its still pretty loud. But his pipe puts out good power it says it puts out between 3-7 HP. Thats pretty good for a pipe.

 

it was full of fluid and i tryed to bleed them again but nothing happened is it true that i could have messed up the whole brake system?

 

Im not sure whether you could have messed it up or not. Does the brake pedel have any pessure when you push it down? If it does and the piston still isnt working you might have. If you dont have any pressure you might want to check your brake lines. If you did happen to mess up the brake caliper I think there only about 40 bucks off of ebay.

 

What do you mean when you say they don't work? Is the pedal soft, are the brakes dragging? If they are dragging, did you loosen the parking brake adjusting bolt? You really can't mess up the brake system by pushing the piston back into the caliper. If you didn't clean off the piston before pushing it in, you could possibly damage the seals. They could leak or not let the piston return when letting off the pedal, but either way could easily be fixed by diassembling the caliper and replacing the seals. No need to buy a caliper from ebay.

 

This makes no sense at all. Not enough pressure to work the piston? You cannot compress a fluid...so regardless of which type of fluid he puts in there it would not matter the first time he hit the pedal. The different numbers on brake fluid represent the boiling point of fluid and whether or not they absorb water not the amount of pressure they can take....


How have you tried bleading it? Did you try using something like a vacuum pump or just pump the pedal and crack the bleader ? I have had great luck with a vacuum pump I bought at sears for $50. It really is handy to be able to blead the brakes by yourself and works really nice on stubborn clutches too. There are also "speed bleaders" out there that I here good things about.

Good luck
