Freshly Bled Brakes

Recommended Posts

Hello,

over the weekend I bled the brakes on my 110 which has disks at the front and drums on the rear.

On Monday evening I set off and tested the brakes before leaving the drive - they were nice and sharp responding crisply to pressure on the pedal. However after using them a few times they have reverted to being a little 'squidgy' . While not as bad as before they are not as good as when I first tried them. The bleeding was done with a Gunsson brake bleed kit and fresh off the shelf unopened DOT4 fluid. (I drained all the old fluid out. )

Can anyone enlighten me as to why the brakes go softer? Do I need to re-bleed or just leave the bleeding things alone and be thankful I have something that works a little better than a rusty ship anchor to slow me down? ;-)

 

regards,

 

Richard

Could be wheel bearings... the wheel is slightly "off true" once driven so part of the brake pad pressure is straightening it up before stopping it.  Whilst testing etc., the wheels won't have been moving.

Have you adjusted the rear drums properly? Often overlooked and makes a big difference.

Firstly, what was the reason for you bleeding the brakes in the first place?

As Maverik says, why did they need the fluid changing? What work has been done to the system? 

Mate they just spongy at the first press or always? If they're just spongy on the first press that would make me think slack in the wheelbearings. If they're continually spongy then I'd be bleeding them again. Making sure all the bleed nipples are fully closed. 

Edited to add, what's the fluid level like? I replaced the rear lines on a friends disco and hadn't quite fully tightened one of the banjo bolts. It gave a slightly spongy pedal on hard braking. Have a look around the system, particularly where you've replaced anything, for any signs of leakage.
