Little help with brakes
Hi I fitted some 4 pots to my other car and new lines and rear calipers iv bled the brakes a few times but they just don't feel right , there not spongy and have a great bite it's just when I'm braking hard from say 70 they don't seem to stop very well it's like the pedal doesn't want to go down anymore but I need it to has anyone experienced anything like this

Ok thanks I did bleed it about 5 times with engine ruining , could there still be air in the system or could be a bad booster , the pedal feels good until you feel you need to brake harder and it doesn't want go down any more but it only feels like it's half way down

Hi I did a few checks today I pumped the pedal until it went hard then turned on the car and the pedal did drop a bit I also sprayed some soapy water around the master cylinder and saw no bubbles and I checked the hose but couldn't see any rips or damage, any ideas what it could be

Yes the pedal will feel spongy you might find you need to get it on a diagnostic machine to cycle the ABS pump. Pressure bleeding at a low pressure and pump the pedal works sometimes but it will probably be a garage job too as people don't generally have them lying about

Ok thanks lads I might just take it to a garage , the pedal feels nice and hard no spongey feeling just to check when bleeding do you start from the furthest away from master cylinder so rear passenger and end up at front drivers and as the 4 pots have 2 nipples do the inside one first then outside and does it make a difference with engine on or off

Generally yes to all the above. The furthest away option was the way I was taught but certain manufacturers seem to have their own ideas. Think this came abut with ABS systems. As for the fronts I just keep going till there's no air for it doesn't seem to matter if you do it by the book you still get a bit of air out of the other side
