ho02pey90 Posted July 14, 2012 Share Posted July 14, 2012 evening all i started this morning 8:00am taking my brake discs of front and rear and replaced them with ebc slotted and grooved discs all round and also ebc red stuff pads, i started with the rear then moved onto the front just as i was finishing the front i noticed something dripping under my car i checked the brake reservoir and it had overflowed and leaked everywhere i soaked up what was left of it till it went to just below max, as i put the wheels on lowered back down the car off the axle stands got in and started her up tried to pull away but it wouldn't move off i want to move i have to really force it because the brakes seem to be locked any idea how this has happened and what my options are to solve it ? Many thanks in advance really stuck here! Quote Link to comment Share on other sites More sharing options...
Ricey Posted July 14, 2012 Share Posted July 14, 2012 When you push the pistons back it can for force fluid out of the reservoir. You topped it back up? Quote Link to comment Share on other sites More sharing options...
Ricey Posted July 14, 2012 Share Posted July 14, 2012 Hmmm just reread Why it it above max after you've lost fluid? Air lock? Quote Link to comment Share on other sites More sharing options...
ho02pey90 Posted July 14, 2012 Author Share Posted July 14, 2012 Hmmm just reread Why it it above max after you've lost fluid? Air lock? i can only guess that when i removed the old pads they were about half worn down and when i replace with new pads and pushed the pistons rite back there was less space in the brake lines, when i replace the rear disks and pads the wheels moved fine but when i replaced the front that when they must have locked up, would an air lock cause the brakes to lock on ?

Ekona Posted July 14, 2012 Share Posted July 14, 2012 All brakes or just the handbrake? Can you spin the front wheels by hand? Quote Link to comment Share on other sites More sharing options...
ho02pey90 Posted July 14, 2012 Author Share Posted July 14, 2012 All brakes or just the handbrake? Can you spin the front wheels by hand? all brakes are locked on i tried spinning front and back separately and both don't have any play, it looks as if the pads are locked onto the discs Quote Link to comment Share on other sites More sharing options...

Ricey Posted July 14, 2012 Share Posted July 14, 2012 You have definitely bought the right discs and pads haven't you? Quote Link to comment Share on other sites More sharing options...
Greekman Posted July 14, 2012 Share Posted July 14, 2012 You need to have the brake fluid reservoir open when changing pads and keep checking it as the fluid level will increase and even overspill!! If you haven't done that and still managed to replace front/rear discs pads then you may have damaged the inner seal of the caliper piston pushing the piston back. The outer seal is dust seal and it would be cracked already unless your calipers are spanking new. Make sure fluid level is at max and lid on. Bleeding nipples all tight. Get somebody to push the brake and check the calipers for leakage. If all ok bleed your brakes....think it's nr/nf/or/of or the exact opposite. I am sure there is a guide in the forum anyway.

Ekona Posted July 15, 2012 Share Posted July 15, 2012 I don't think it's a case of not capable, it's either ignorance or forgetfulness not to remove the brake fluid reservoir cap. Greekman is spot on about the possibility of rupturing seals, but tbh I'd have thought it would be nigh-on impossible to push the pistons back in with the cap on (especially by hand), so I suspect that the OP did remove the cap.

Yeah, and I'm looking right at you when I get that exact impression. If you aren't capable of posting something useful, then don't. The OP asked for advice, not for comments on his abilities.

nzr350z Posted July 15, 2012 Share Posted July 15, 2012 Understand your comments,but isnt removing the brake fluid cap and checking the level while doing discs and pads the most basic thing to check? Quote Link to comment Share on other sites More sharing options...

Ricey Posted July 15, 2012 Share Posted July 15, 2012 Understand your comments,but isnt removing the brake fluid cap and checking the level while doing discs and pads the most basic thing to check? Totally basic.......so again lets go back to the fact that your comment is still patronising, condacending and largely pointless. You only learn by making mistakes and receiving useful advice to rectify them.......not from receiving comments about how 'capable' you are.

trackpig Posted July 16, 2012 Share Posted July 16, 2012 Op- I think your new pads are just tight in the calipers. Remove the pads from each caliper and use a hand file to remove the paint and a fraction of the backing plate where the edge of the backing plate of the pads slides in and touchs the caliper( the leading and trailing edge of the pad- not the friction material itself). Also make sure the caliper is free from debris in the same area. Once this is done the pads will be able to move in the caliper correctly. Reassemble and test that corner before moving to the next.

Daryl Posted July 16, 2012 Share Posted July 16, 2012 How hard have you tried to move the car? I left mine on axle stands for a week with the wheels off while i detailed the car. The first time i tried to move the car it wouldnt have it, (using just the clutch) I had to give it a few k of revs and force it to move. Maybe worth giving it some more ooomph and see how you get on. Well thats what id do. Quote Link to comment Share on other sites More sharing options...
