strange brake problem!

[alan b]

hey lad i out new opel discs and pads on my nova a few days ago along with new brake lines and new fluid, but ive done around 150 miles and there shocking, i mean theres nothing in them atall ! ive blad them out and theres no air in them and the pedal isnt going out from under my foot or anythin!? maybe just longer to bed in?

[Welsh Dan]

Did you degrease the discs before you fitted them?

[alan b]

yerp think i did!?! i used thinners, would that have been ok?

[Welsh Dan]

That should have been ok, get yourself a can on brake+clutch cleaner and a roll of kitchen roll and give both sides of the disc, and the pads a thorough cleaning. If the pedal is fairly firm then its not likely to be a hydraulic issue. Check for leaks though just in case.

they probably need bedding in...

get them warm by doing 30-5mph stops, then after about 5 of those do some firm (not heavy) 70-30 decels. once heat is built up a few times do some keen 70-near stopped runs (2-3 should do). DO NOT stop fully.

let the system cool down and you should be fine then.

are they std pads?

[Adam]

As above.
When bedding them in harshly, dont bring the car to a stop with the brake pedal, as that puts deposits on the discs, which lead to them "warping", even tho they dont actually warp.
