Boas pessoal, como posso melhorar o poder de travagem do meu panda, eu sinto k o carro so trava praticamente com as rodas da frente, se fizer uma travagem mais agressiva mas sem derrapar a frente baixa mt e as rodas de traz ñ ajudam, alem de o pedal estar mt rigo. Levou pastilhas e calços a pouco tempo Ja sangrei os travoes atras, tou a pensar mudar o oleo para dot5, e ñ sei mais o k fazer, o meu carro e de 88 hainda ñ teem servo ao freio.

Brakes

My experience with the brakes is that they are OK when working properly. The sliding caliper set-up corrodes up. Gives you half the braking effect for the effort, and wears out the (very expensive) hub bearings. If the inner pads are worn more than outer things are sticking. An hour or twos effort dismantling, cleaning, and reassembling with "copper ease" or similar on the bits which need to slide helps. You also need all the surface area of the disk: My CLX had disks which were badly rusted in from the edges. 30 UKP got me a pair of new disks and a set of "pagid" brand pads from a motor factor ( APE in Erdington, Birmingham ). They were not too difficult to replace, once I'd worked out which bolt to undo which wasn't mentioned in the manual . The brakes are nice now, and don't come as much of a worry after driving with a servo. But I do wind the window the wrong way ;-) I believe it is possible to fit a servo from a donor (Panda4x4/Uno), but is more work than I'd consider. Your enthusiasm and skill may well exceed mine :) Also while you're at it, check that there is no air or water in the brake fluid. Get the brakes bled if you're not sure. I've found that with a small amount of any kind of impurity you don't always have a spongy pedal but brake efficiency goes right down! Also check the pistons aren't sticking. This usually results in pulling to one side during braking, but not always ... Also again (and this is the last one honest) check that your disks are not too thin even if not corroded, as they will get hotter quicker and the pads will not bed in properly. A glaze will build up, again reducing brake efficiency!

John H, I'm glad you found which bolts to undo - but in my experience they are an absolute PIG to undo. They were so tight that I actually bent my 3-foot breaker bar. You need a lot of grunt and muscle power - I'm 6 foot 4 and 14 stone and even I found it difficult. Don't we all wind the window the wrong way? Or is this a reference to something I'm not aware of? ;)

Querem maiores?

Bigger brakes

3G: grooved discs only.

Black Diamond: grooved, drilled & grooved, just drilled. (this discs are all in black)

Brembo: grooved (Brembo Max), drilled (Brembo Sports).

Red Dot: drilled & slotted, 2 kinds of grooved discs (different patterns).

From what I've been told these discs are not bad, and together with some good pads (green stuff ones are excellent!) they should make any panda to brake MUCH better. All this discs are 240 mm diameter!! I think that they will only fit Fiat PANDA 1.1 & 1.1 4WD from 93 to 95. Other Pandas should have to upgrade to 1.1 calipers, if these are different, or just the caliper support, but I don't know the difference between the two so...

Note: To install bigger discs the caliper supports have to be fabricated and bigger calipers installed, if I was going that far I would definitely install the brake master cylinder, servo and calipers off an Uno/Punto and maybe place rear discs as well. (Reason being the stock master cylinder simply sucks, even with a servo and bigger discs just ask anyone with a Selecta!!)

Better brakes

I've been looking after two Pandas for a while now, and have finally got to the bottom of why the braking effort required is so different between the two (neither of which have a servo). The one I use as my daily driver had some "Pagid" pads and new disks fitted when I got it, and it stops quite well: you don't need to do your Bruce Lee impressions to stop it, and you can lock the fronts up on a dry surface if push comes to shove.  But the other one (which my daughter crashed the other day, because it wouldn't stop...) has never had the same feel to the brakes, despite lots of cleaning of the sliding bits, and lots of "copper ease" on reassembly. Today (having got it all straightened, and glued back together again) I thought I'd have another go at the brakes on the daughters Panda and replaced the FIAT pads with some BOSCH ones 9.99 from A.P.E. in Erdington - cheaper than Halfords own brand), I had wanted the Pagid ones so I could compare like with like, but they were out of stock. Anyway, having got them somewhere near bedded in I reckon the braking effort is now broadly similar between the two. a lot better than it was :D Moral to the story, if you want to stop a Panda (or have a handbrake that works on a Cinq, from what I gather in the other bits of this forum) you need something grippier than FIAT standard parts. I understand Pagid is German as of course Bosch is - I think they know about the need to stop

espero que isto te dê uma ajuda, pelo menos até eu acabar o meu artigo :t_up:
