Figured it would just be a bad bias. When I fitted the braided brake lines it felt odd, so a mate handed me over to a bloke and he adjusted the balance bar. But after heading on track after 4 laps it began to snake! So put it down to naff discs, Squirming under braking is not fun.

I'm still running the 1.1 lines, with 266mm setup up front, and your drum rear beam afaik the shoes and drums are perfect. I drove back from brum last night and my brakes performed better than ever when entering northants, especially when slowing from 50 to 0 within a split second.

Cheers Tom I appreciate it, and on the cat side of things I may chase you up on that as it's finally going decat this year anyway!

Rudpud, yeah I know it's just useless labour and they're just trying to rob a "typical young saxo driver" I've just insured the car for a year so I'm not going to be scrapping it

Been to a slightly more trust worthy garage that I have used for around 5 years and have worked on my families cars for the past 10, they looked at the rust and gave me a price of £65 and then tested the brakes on the rollers, they found that the front brakes are fine! I also monitored the readout and both read fine! So god knows what they're going on about that. They then tested the rear brakes and they were totally out of balance.

They are now sorting the welding and rear drums, the drums were actually leaking at the cylinder and were causing slightly more travel in the pedal. But it was only minor, otherwise they're now balanced up and reading correctly.

I'm going to grease up the sliders up front, then wind the piston back and ensure it works as it should and isn't seized, and just generally clean the brakes so it makes it look like they've been taken apart! If they're fine theres no need to fiddle imo.

As for the cat I don't know what to do there. I could fork out £50 and fit a new one, but considerring I want a decat anywho it seems foolish lol!

Honestly buddy, fook the £50 just pop to stourbridge, borrow mine, just let me know when you need it

Cheers Tom, sad thing is I'm unable to drive up to Stourbridge and if I did it'd cost me £40 to get there and back. Cats on ebay from downpipe to backbox are just £50. I'd buy it and wrap it up till next years MOT

Otherwise:

Update in full:

Car's came back today, got the welding sorted (and they did an ace job, much better than last time) and the brakes so that's two things sorted, it is now braking straight and true on my usual garages rollers after a test but I'll grease up the front brakes just to save arguments with the other petty garage.

I've now got my emissions readouts next to me and deciding what to do here as tbh if a bit of exhaust putty was applied to the leak around the cat join (looking at it today it appears that where my car has scraped going over a bump in the road it has caused the old putty to fall off, hence the leak!) and the car was warmed up significantly before the run I reckon it could pass.

The fast idle test was as follows:

CO = 0.459 fail
HC = 23 pass
Lambda = 1.053 fail

For those that don't know the CO is out by 0.159 and the Lambda is out by 0.23 here.

Second fast idle:

CO = 0.357 (so it was a tad better, out by just 0.057) FAIL
HC = 78 pass
Lambda = 1.133 (worse but out by 0.103 here) Fail.

It passed the natural idle test.

In comparison to last year (overfueling; braking the Emissions reader and forcing my usual garage to spend 2 grand on a new machine ) it's not bad and the lambda readout can be sorted by fixing the leak just after the lambda sensor. But as for a new cat? Really neccessary? I have a day to decide.
