Brake help

[The Boosh!]

Hello. Just changed the brakes on my gfs car, but they feel shite. Barely work in fact. AFAIK I have done everything right. They also make a noise when she drives. Any ideas

take the car for a drive and hit the brakes hard, the pads have some brake in layer on top that needs to come off.

 

[The Boosh!]

So it will just fix it's self yes?

 

[mr.valver]

You did clean the discs with brake cleaner first didn't you ? lol

 

[Kizza9]

i never cleaned my discs when i changed them and they were fine. Could there be the possibility that air got into the brake line? could also try what james said and just wear the brakes in

 

[James.f]

ye, just go for a quick blast and hit the brakes had you will have them back.

you didn't disconnect the brake line to the caliper no?

Whats the point? the pads are just going to rub all over the disc when breaking anyways

Pads on the wrong way round? lol

No didn't disconnect the brake line and didn't see or feel any fluid leaving the brakes. Brake fluid is also still at the same ish level. :S il go for a drive and hope they bed in

Need abit to wear in, did you have to push the piston back in as well?

 

[Da]

You put the lid back on the fluid reservoir Luke?

Is there no feeling in the pedal at all? One or two presses with the engine running should get the servo going and the pedal will go hard.

The discs are covered in machine oil from the factory to stop them from rusting before they are used, this needs to be removed with meths or similar otherwise it'll contaminate the pads and is probably why the brakes aren't the best tbh. See what happens but will want the discs cleaning and a new set of pads at worst if it doesn't improve.

Every set of brakes i've ever fitted to any car have worked perfectly well from day 1, theres never been any real "bedding in" need. I know they do but its not a complete night and day difference with normal standard compound pads.

 

[The Boosh!]

Da, yes put the lid back on it. Although I think it's fooked as it doesn't screw tight. Gets to a certain point the goes lose again.

Ben yes I had to push/hammer the piston back. It was proper jammed too on the drivers side

 

[Da]

Could be a seized caliper then if the drivers side was difficult.

 

[172Ben]

Should be resistance when you push, but with the cap off it shouldnt be to hard.

 

[Da]

No signs of any fluid leaking out anywhere?

 

[The Boosh!]

Nope. Deffo 100% not leaking brake fluid...

I didn't replace the disk's, they were fine, no grooves in them and smooth as a pornstars vag.

Il give them a few days to bed in then wack them back off if they haven't improved. Really don't wanna end up having to bleed the lines

 

[scotty2hotty81]

cap on or off makes no difference to braking.

most disks should be cleaned with brake cleaner before fitting due to being covered in a oil based coating to stop corrosion.

when you fit disk/pads it can take a little longer to bed in.

if your still having issues just bleed the brakes, i did rears on a vectra 05 plate a while back and lost all braking power, full bleed sorted it out, still to this day cant understand why but hey ho :approve:
