........got 6 pots on the front and i've noticed the past couple of weeks they dont feel so good..................did a few tests today and they just dont seem to be gripping as well as they did.............recent pad n rotor change..........the car would allways lock up if u pushed too hard but now its ........er......crap..............advise please and also what kind of measurement should they be getting on the brake rollers in a m.o.t bay............before the PRICKS start they are hi-spec 6 pots 335x32mm.........cheers Pete

change the fluid first of all

and while you are doing that, make sure you put the pads in properly and didn't disturb anything else on the calipers

C4llyT

Yeah fluid, can drop boiling point 100F in a year, and you no doubt been giving it a hard life

.....aint that the truth............

C4llyT

Well then again must have decent fluid in there, so will stand up to it better, but still can affect it.
On the rollers, depends on many things.
Looks like you've wide tyres - reading is restricted to the grip, unless brakes are utter wank, I'd say 300-350, no higher as not heaviest of cars.

.......thinking about it, it has had fluid recent aswell cos the hand brake was shite...sticky caliper came off...........i only use dot4 fluid but they've allways felt strong............i'll take the calpiers off and grease the pistons,new fluid..see what happens..............cheers

C4llyT

You want 5.1 then, dot 4 is for normal driving, not some northern maniac
5.1 is cheap, try GSF for the ATE blue stuff, tenner for 1 litre and know when it's through.

.....see i got told not to bother with 5.1...........something to do with condensation/water build up in it.................better start another thread.........................

.........................not fuckn likely.........i was going up n down today from 100 - 160 testing my brakes...thinking........"they feel shite"................

C4llyT

What and it being much better than dot4?
They all absorb water, are all ether based.
Castrol SRF is best on the market.
Changing yearly won't have any problems unless you've overheated them, and then just bleed a bit out.

Silicone fulid doesn't absorb water, and last the life of the car.
tabetha

righthooker

May not absorb water ,but wont last the life of the car,mate boiled his on saturday and flushed it out as it was fooked

BigErn

Isnt it DOT 5 fluid that people say not to run whereas 5.1 is fine?

I had standard calipers on my last one, stripped and cleaned them up, replaced all seals and used 5.1 fluid in them and they were fookin mint.

Maybe your calipers need a service mate and a fluid change.

C4llyT

Yep.
My standard car will lock up at 100 in the dry.
Even before decent fluid and braided hoses.
And the brakes are often slated to fuck.
Fluid is biggest factor in all this I'm sure, unless fucked the pads, not too clued up on that.
160-100 repeatedly jumping on them can't hurt though

what pad compound are you using

pete mcrash

ds2500 front n back..............all canny new aswell................

C4llyT

I'm sure you've fucked the dot 4, is first upgrade I make, costs a tenner for the 5.1 and not long to change and is easy.
160-100 several times could have fucked it, sounds ridiculous I know as it's put in run of the mill cars to do just this
Lol!

in the garage on friday...............calipers stripped,pistons red greased....and dot 5.1...........cheers for ur help

C4llyT

Anything to do with calipers or pistons you'd notice uneven braking, or pulling to one side, one wheel getting a lot dirtier etc.
Doesn't hurt though, and nice to see someone making effort to maintain their brakes!
