Question Pumping the brakes??

Just a quick question, I had my pads done on sunday but now the brakes feela bit spongy to say the least, is there anyway that i can "tighten" them up a bit, without getting too mechanical?

Cheers,

Neil.

Was it just the pads that were replaced?

A spongy pedal usually means there's air in the system. I assume they didn't bleed the brakes or change the fluid?

He probably took the cap off to push the caliper piston back.
Sounds like your fluid is due for a change.
Easy enough to do and makes a big difference on pedal feel.
If your not up to DIYing it a local garage will probably only charge an hours labour plus £5 -£10 for the fluid.

It's the resistance to compression in brake fluid that gives you the firm pedal. If there's a more compressable liquid or gas in the brake system, then this will have a direct effect on the pressure you apply on the pedal and the actual pressure applied to the caliper pistons.

It's pretty straightforward to dom but like most things it's down to experience and confidence. You could simply get a local garage to bleed the brakes and top up with more fluid, but you'd be much better getting them to completely flush out the system and re-fill with new fluid.

Fluid costs between £5-£10 per litre and you would need about 2 litres to fully flush the system. I guess a garage may charge an hours labour (should take much less than this), so add £20-£30 labour on top of the cost of the fluid.

A Dealer would probably charge you £100 to do it all
