Bleeding brakes

In a word, no ! I've found in th past that gently tapping the calipers (4 pot brembos) can help, as well as doing a number of purges with an easibleed . Yours Chris

Great thanks.

If u have time, putting some gentle heat into the calipers can also help too with a blowtorch but generally speaking bleeding the system is pretty straightforward !

Does anything fancy need to be done regarding the ABS when bleeding the brakes?

Cheers,

Tom.

The only thing to add to what has already been said is that if you bleed the brakes, they can still feel a bit spongy. If you re-bleed them the following day you find there is yet a small amount of air to come out of each bleed nipple. My guess is that small bubbles can sometimes catch on the sides of the calipers and take some time to float to the top. Thumping the calipers with a rubber mallet while doing the job can help to dislodge them (a bit more than the 'gentle tap' as espoused by Mr Graham!), but it's not 100%. Oli.

The best time to bleed brake is when new pads have been fitted although this is not always convenient. It pushes the pistons back into the caliper so reducing the void in which the bubbles can stay trapped. I suppose taking this to its logical conclusion you could insert wooden wedges to hold the pistons right in but then again, a good bleeding aid like the Gunsons eezibleed probably renders that suggestion overkill. I like the idea of giving them another go the day after like Oli says, because although the brakes bite on my cab they do feel spongy, after having the plate lift sorted, (I know shame on me for paying an indie, but I dont have a mig welder to tack a nut on the head of the bolt) , but a bit tough on the wallet if you are getting your indie, or indeed a Porsche centre to do it

Highly recommend a Gunson Eezibleed. It has the right fittings for a 944 and makes the job a doddle. Vacuum bleeders don't work very well because they pull air past the threads of the bleed nipple so you get neverending bubbles!

Quite so, and I use it to replace the oil in the gear box on the AX GTI as well the give it a thorought wash in soapy water then meths then dry it so as not to contaminate the brake fluid next time. Always use brand new freshly opened fuid and not from that old tin knocking about at the back of the shed, because however hard you try it will absorb moisture and do not use bleed-off to top up the master-cylinder as it will contain bubbles
